NEW YORK -- There she was in all her glory: Serena Williams in her skin-tight black cat suit that, when the light struck just right, made her appear nude. A major spectacle? Nope. Just another day in women's tennis.

	After adding hot pink accessories, Serena Williams said she cares about every clothing detail.

Meanwhile, on the next court over, Tommy Haas was told to remove his muscle shirt. For heaven's sakes, it was sleeveless!

"I asked them what was appropriate on the women's tour," Haas said. "You see Serena and some of those ladies wearing all this tight stuff … It's interesting, it looks good."

Three days into the U.S. Open and the fashion police are out in full force.

Wednesday's media clippings were full of notes on the latest fashions in women's tennis, with Serena's S-curves leading the way.

But one of the most interesting shots was in the New York Post, which reprinted a photo of a nude Tommy Haas serving as a frame for his equally nude girlfriend, with his arms covering her exposed breasts. ("At breakfast I saw it. It was a good wake-up call," Haas said.)

Take that ladies! The guys can be sexy, too. Well, unless it's deemed that they're not wearing "clean and customarily acceptable tennis attire" -- as specified in the Official Grand Slam Rule Book -- by tournament referee Brian Earley and tournament director Jim Curley.

So Haas donned a shirt with sleeves -- changing on the court, mind you, to the sound of wolf whistles.

After crushing Dinara Safina, Williams, still looking like she was dressed by the Tuscadero sisters, addressed this seemingly double standard.

"I think for the guys and the ladies, you should wear whatever you please," Williams said. "Someone can't tell me what to wear. I hate when people tell me what to wear."

"There's some interesting outfits out there, I will say that. Pretty revealing," Pete Sampras said smiling, when asked about Haas' quashed fashion statement. "You see all the curves."

Williams did submit her outfit for approval -- Haas apparently was unaware there was such a thing as an approval process -- but it seems unlikely that at this stage his shirt will be allowed even if submitted.

	Luckily, Tommy Haas had some other shirts with him to change into.

While the women's fashions seem to shrink every week -- shorter and tighter -- the men traditionally wear baggy shorts and untucked, collarless shirts. And the numbers show that more and more people these days are drawn to women's tennis. With hot American draws Sampras and Andre Agassi getting ever closer to retirement, criticism has arisen that the men's game isn't, well, as attractive.

"There's no question we've been hearing a lot of not so flattering things about the men's game compared to the ladies," Sampras said. "Maybe it's an effort to do some different things."

"If you see some of the stuff (they've) been wearing on the women's side," Haas said, "you have to give them credit. They're probably ahead of us for sure.

"But you know, that's something maybe for us to look at and to see what we can do. I think that's definitely a way to start off. I'm sure some people will like it."

Williams, the No. 1 women's player, said the women's unusual outfits might encourage more people to watch tennis.

"Maybe more people look, see how nice it is, how fun it is," said Williams, who frequently designs her outfit, although not the latest. "It's all fashion to me. It's all strategically placed, everything I wear, even the socks."

But 13-time Grand Slam winner Sampras doesn't think more style is what's needed to help build a new image for the men.

"You know, it's about the tennis. It's about a little personality," said Sampras, who like Haas is represented by Nike. "But I don't think -- (it's) something I wouldn't feel comfortable doing. But I'm sure Nike, you know, wants to make a statement. Maybe so does Tommy.

"But that doesn't work for me."

Haas -- emphasizing that he was not joking -- said he had a serious tennis-related reason for wanting to bare his biceps.

"In my case, it really helps me because the shirts, the sleeves sometimes when they get really sweaty, they get in my way. That's one way to stop that."

Williams, who also has budding hopes of being an actress, agrees that on the court fashion distractions and starlet aspirations disappear. She gets down to business.

"When I'm in a tennis tournament, it's all about tennis, especially nowadays. I'm so focused on tennis. I'm very focused on what I want to do, how to be the best."

And, with the exception of Anne White, some of the biggest fashion changes in tennis have been made by the best players -- like Andre Agassi and the Williams sisters.

"If you look back many years ago, you had to wear collars," Haas said. "It was usually the short shorts. That was the traditional type of style. Used to be only in white.

"Then Agassi came along, other people came along. Times change, like in everything else. Tennis changes. The game changes. Why not change a little bit in the stuff you wear?"

Haas said he was sure that in 10 to 12 years male tennis players will likely be wearing sleeveless shirts if they wish. But if Sampras' expected baby were to be a girl, would he someday let her wear a black cat suit on a tennis court?

"I might draw the line there," he said.
