Serena Williams will certainly go down in history as one of the most legendary American athletes ever. Her achievements in the world of tennis are near unrivaled, and she's only bested by former Australian player Margaret Court in Women's singles.

She's not far behind either and is just one Grand Slam away from tying Margeret's record of 24. It will be quite interesting to see if she does go on to tie and even surpass the mark before she decides to call time on her career.

Apart from her reputation as one of the world's best tennis players, Serena is certainly the most attractive. The 36-year-old has wowed just about everyone over the years with her remarkable physique and sense of style. She does possess the most attractive butt in all of sports, and is not afraid to remind us from time to time, always coming up with some outrageous outfit that leaves jaws dropping all around.

There's definitely a whole lot to choose from, but we've tried to come up with 15 of the very best. So prepare to be amazed (and a little turned on) as we take you through one of the best Serena compilations you'll ever see. I promise you won't regret it.

15 15. The Catsuit

Serena was so dressed to kill in this pic - or possibly just out to look better than big sis Venus. The pair had stepped out to a party in New York City to commemorate their appearance on the cover of the popular Hamptons Magazine back in 2011. And the younger Williams sister made sure to really look the part.

I'd say that she got it about right, with even her curly hairstyle doing her some real justice. But of course what really stands out are her famous curves, which were hugged and accentuated by the remarkable choice of outfit.

The tennis star definitely outshone her older sibling on the night, as Venus went for a more modest look, donning a short multi-colored dress with gold shoes.

14 14. So Pretty In Pink

Ever seen a pink leopard? I haven't either, but I have seen a pink panther, as I'm sure you have. The fact that Serena's wore pink leopard print does make it look so very natural, but why would we even notice that when there are better sights to behold down below?

Serena didn't bother to hide much of her skin on the day, competing in a US Open semi-final match against Russian leftie Ekaterina Makarova in 2014. The American star won said match and went on to beat close friend Caroline Wozniacki in the final to be crowned champion.

She did not lose a single set in the entire tournament and didn't lose more than three times in a single set, making the whole thing quite memorable for herself, as well as fans.

13 13. Leopard On The Beach

If nothing else, Serena Williams surely loves her some beach time. There are probably hundreds of photos of the 36-year-old hanging out on the beach, wearing very little, and flaunting her voluptuous bod. So we did have plenty to choose from.

So why this one? Hey, with the amount of Serena beach pics out there, it's just on personal preference. Forgive me if I'm wrong, though. But there are several other photos below anyway - couldn't get em' all wrong now could I?

As you can probably tell, this one is already a few years old. But my, is it something to look at. Serena is never shy about showing off her physique on the beach and there's always plenty of paparazzi around to capture the moment.

12 12. Lady In Red

Serena is known for her love of red dresses as well. They're said to be among her favorites, and with good reason, as she looks darn good in them - although that's hardly an argument; she looks good in everything.

This particular one, however, really shouldn't even be legal for her to wear. By no means am I complaining, though, it's just really, really painful having to see such perfection sometimes.

Serena would have certainly outshone the likes of Gabrielle Union if she was around for this event, which we assume was a Macy's thing from the background. But wow, she really knows how to rock a dress. Whether she's in her tennis outfit or walking a red carpet, Serena never looks out of place.

11 11. More Leopard Print

This one dates back to 2009 when Serena attended a party in Miami to party to celebrate the kicking off of the Miami Open hard court championship (Sony Ericsson Open), along with her sister Venus. Of course, she was the best-dressed sibling, coming out in her tight-fitting leopard-print dress with her hair did, Marilyn Monroe style.

Venus and Serena were competitors in the semi-final of the aforementioned tournament that year (2009) and the star of this list beat her sister to advance to the final. She couldn't get over the last hurdle, however, stumbling in a loss to Victoria Azarenka.

The sisters also faced off in the Barclays Dubai Tennis Championships, Wimbledon Championships and the robin-round phase of the Sony Ericsson Championships that very year.

10 10. In Heels

This pic was probably taken in a promotional shoot. Serena is good, but not good enough to win a professional tennis game wearing high heels and a tight dress - although you never know.

She is, however, hot enough to rock this get up with a racket and look darn good doing it.

Serena will admit to wanting to look like her sister while growing up, but is obviously happy to be who she is now.

"I was 23 when I realized that I wasn't Venus. She's totally different," she once said in an interview. "I'm super-curvy. She's tall and she's like a model and she fits everything. I was growing up, wanting to be her, wanting to look like her, and I was always fitting in her clothes, but then one day I couldn't. But it's fine. Now I'm obviously good, but it's a weird thing."

9 9. That's Why They Call It The Blues

Well doesn't this just bring tears to your eyes? It really should. The tennis fashionista has always found ways to keep us piqued as it relates to her outfits both on and off the court, and she truly outdid herself with this one.

Sporting blue booty shorts and not much up top, Serena must have dazzled just about everyone on the day. Rappers Common and Drake were said to have been beefing over the star around that time, and it's really no wonder.

Common, who has dated Serena in the past, later admitted that his beef with Drake may have been over the beautiful Los Angeles native.

"At that time, I think it was the Drake-Serena situation," he explained. "I didn’t know what was going on with that. And I ain’t know if he was throwing shots at me. [Serena] my ex and we’re going our separate ways. So, unfortunately, the war might have been over a girl, but at the time I never said that. It wasn’t totally that. It was more of, 'Do you respect me? 'Cause I actually like you as an artist.'"

8 8. The ESPYs 

Serena wore this revealing pink dress to the ESPY Awards in 2011, and people still haven't forgotten it. The said outfit showed off some remarkable action up north, while also hugging her lower half.

So by now, you know that she has quite a lot going for her, but she says her smile is her favorite feature.

"Since I don’t look like every other girl, it takes a while to be okay with that," she said before the event. "To be different. But different is good.  My smile remains my favorite part of my body. Does that count? I think a smile can make your whole body!"

Anyone who looks at Serena walking a red carpet and could possibly deem her unattractive is baffling, as she's shown time and time again just how stunning she could be on and off the court.

7 7. Denim The Menace 

We're not sure what look Serena was going for here. May have been something to the effect of Serena Warrior Princess, or a Bounty Hunter get-up - possibly even a different Wonder Woman sort of thing. But whatever it was, it must have helped intimidate the opponent.

Serena is the type of athlete that still manages to surprise you when you think you've seen everything she could possibly throw at you. And this was on a whole new level.

The superstar marched out onto the court wearing what your teenage daughter may typically wear to the nightclub, and actually played a match in it. This all happened at the 2004 US Open, a tournament she failed to win, though, exiting during the quarter-final stage.

6 6. Just Do It

The younger Williams sister wore Nike's grey and pink apparel during the 2013 US Open, and there's hardly any doubt that she was the best looking female athlete of the tournament. She was also crowned Women's singles champion, defending her title against Azarenka in the final.

"It is a tough loss but to play in the final against the best player in the world is unbelievable," Azarenka said after the match.

The achievement left Serena at with her fifth US Open top accolade, as well as her 17th Grand Slam championship. While the outfit pictured up top must have made the particular game an unforgettable one for male viewers. There's no doubt any Serena match is must-watch television. You wonder if we'll ever see someone as dominant again.

5 5. Just OMG

Never a dull moment with Serena around now, is there? The 23-time Grand Slam champion was called upon to announce Beyonce at the 2016 MTV Awards and ensured she looked the part, wearing a knee-length, cut dress that exposed unexpected parts of her body.

Serena has gone through a remarkable transformation, growing the confidence to show her body off wherever she goes. And she's also shared a bit of what keeps her looking this good.

"I don’t even know the D word," she once said. "Smaller portions of every meal, a lot of grilled or baked chicken or fish, and steamed veggies.

"But I can never turn down a good piece of cherry pie. All I know is that in 10 years, I don’t want to be as wide as this couch."

4 4. Flexibility

If any of the outfits above left you gasping, you'll probably be needing a moment now.

As hinted before, Serena wasn't always this brave when it came to showing her body off. Here she's also showing off her athleticism, providing an amazing display of her flexibility. A lot of people may look at Serena and just see her as being thicker than most female athletes, particularly in tennis, but this pic shows you shouldn't let her muscular frame fool you. She's an incredible athlete and is looking a lot more flexible than most athletes would. There's no hesitation on our part in saying Serena may be the most gifted female athlete the sport of tennis has ever seen. Can we get some more photoshoots like this?

3 3. Mirror Selfie Goodness

The 14-time Women's doubles winner shared this mildly raunchy photo on Instagram, showing off her provocative curves in what appears to be a bathroom mirror.

If there was any doubt that she was being a tease, the caption erased all uncertainty by including the caption: "Look back at it." Serena was rumored to be seeing Canadian rapper Drake at the time, and the caption was seen as something of a message.

She's now married to Alexis Ohanian, who is the co-founder of popular social news aggregator reddit, however, and the pair had a beautiful baby girl last September.

The above pic, though, is really something. And the look on her face makes it even more attractive - I really don't think I need to explain why.

2 2. That Leotard

Serena has never been one to shy away from making a fashion statement - well since she got over her confidence issues. And she did just that some years ago when she tweeted this photo of herself in a bright pink leotard to mark her return to the court after spending some time out dealing with health issues.

The player had been diagnosed with blood clots in her lungs and had spent several months sidelined. She did bounce back quite well, though, and got right down to business with a statement of a snap.

Unfortunately, this is the only angle we have and you can't really see the goodies how I know you'd prefer to. Yet it's still a really great pic and there's still a superb curve on show.

1 1. The Other Catsuit...

We started with a catsuit, so it's only fair that we end with a catsuit. And, admittedly, the placement is also in an effort to save the best for last -  although I'm pretty certain it would be extremely difficult, if not impossible, for many of you guys to choose a winner from this list.

This particular outfit, made by sportswear giants PUMA, was designed with the help of Serena herself, and it was a damn near perfect fit. I only say 'damn near' because it's probably a tad too long. But anything shorter would definitely have children banned from viewing tennis in many a household.

The tennis icon did face some criticism over her choice of outfit, yet I doubt she cared too much. And frankly, I don't either.
