Thong Underwear Trends - Wearing Thongs No Longer Trendy - Cosmopolitan A little more than 10 years ago, the Macarena was a hit, the Rachel haircut was in, and wearing a thin strip of fabric between your butt cheeks was considered daringly sexy. Thankfully, the dance is now socially unacceptable, and those layers have grown out. But what about the thong? Although our love for it has endured, its popularity appears to be fading, and recent figures show another style is taking over. We conducted an investigation to find out how thongs went from hot to not and target the man-melting undies you must own now. No doubt, male fans appreciate the fact that boy shorts make our asses look so amazing. Let's face it, unless you're blessed with Giselelike DNA, it's likely that a string bisecting your backside wasn't doing your figure any favors. Most boy shorts have a seam running down the middle of the butt, which accentuates the curvature of the bum for any body, giving the illusion of a Kardashianstyle keister, says Campello. And even seamless boy shorts enhance your bootyliciousness by exposing the very bottoms of your cheeks. "For a man, seeing that part of the buttocks is a great turn-on," says Daniel G. Amen, MD, author of Sex on the Brain. "His mind wants to fill in the rest of the picture." The final thing the boy short has going on that the thong doesn't? It doesn't give you a permanent wedgie it's actually comfortable. And can we just say boo-yah to that?
