How many sit-ups do you think I'd have to do every day to get a stomach as flat as this model's? Nevermind. Let's focus on the bathing suit, shall we? It's eyelet, just like a whole lot of other items you'll be seeing in stores and on streets this spring and summer. It's not just for curtains, tablecloths, and baby's bonnets anymore. This year, eyelet is popping up all over the place:

JCrew couldn't even keep this eyelet purse on their virtual shelves — it sold out immediately, but if you call them they may track it down in one of their stores.
