We loved the retro '50s feel of the crop top when it appeared in Rachel Comey's Spring 2011 runway show, and we've since seen it popping up on celebs. Kelly Rowland chose a yellow lace version, while Zoe Kravitz went for a white top and black skirt at a party in New York. We even did a story on how to wear a crop top. That said, it definitely shows some skin. Is it a trend you'll be wearing this Summer?
