We could just say, "Well, Beyoncé wore one, so you should too," and leave it at that. But seriously, we've come to the following conclusions: A) "Single Ladies" was ahead of its time, and B) this piece is will be your saving grace this winter. We've found that bodysuits are the answer to our sartorial prayers. Not only do they stay in place when tucked into high-waisted pants and skirts, but they're also thin enough that they don't add any unnecessary bulk. Under pretty blouses, the extra layer will keep you oh so warm and extend the life of your favorite summery tops.
Go on to see how to layer this hero piece all season long.
