When it comes to crop tops, there are a million ways to slice it, cut it, tie it...as long as your navel's getting some fresh air it's sure to be literally cooler than most other upper-half clothing options. But a word of caution coming from someone who's murdered drawerfuls of once-favorite t-shirts: leave the scissor work to the professionals. You'll be kicking yourself when you realize that you have nothing to wear with all your mid-rise and lower jeans, and if history repeats itself—and it always does—2003's low riders will be back in full force in about 10 minutes. So hurry up and fill your carts while you can still get some use out of those elevated waistbands:
American Apparel V Strap Tank : Or really anything from American Apparel, they have a huge selection of crop top colors and styles. They're all pretty great, too—especially for those that like to go commando up top, because the AA cotton/spandex collection of crops are basically pullover bras. The V Strap tank is a newer design with a collarbone-grazing neckline, cute back, and thicker fabric that leaves a little more to the imagination than, say, a thin-ribbed tight white baby tee...but not much.
Need Supply Co. Scout Top : I'd argue that while all crop tops are casual, not all can be dressy. The Scout Top can go both ways—pair it with oversized khaki slacks and whatever Birkenstock incarnation you prefer, or with a tailored pencil skirt and heels.
Reformation Castelli Top : A hybrid wrap/crop is so painfully disco. And being disco is so painfully cool. Plus, you can wear full-support bra—straps and all.
Asos Crop Top in Wide Rib with Zip : The unexciting name really speaks to the workhorse nature of this piece, which, while it might go underappreciated at first glance, will surprise you with how often you find yourself wearing it. Top? Absolutely. Cardigan? Just unzip it. Is it too cold? Not if you're in this top, because your shoulders are covered. Is it too hot? Not unbearable, because the sleeves only go to your elbows...and it's a crop top. Also it's grey, which is the blue denim of knitwear—it goes with everything.
