It looks like it would chafe, too.

Hark! A Vagrant author Kate Beaton recently produced an absolutely glorious flurry of tweets about the upcoming TV adaptation of Marvel's Cloak and Dagger, a comic book series about a crime-fighting duo consisting of a man in an enveloping cloak and a woman in a skin-tight bodysuit with a deeply impractical dagger-shaped cutout on the chest (which Beaton describes, aptly, as a "tit window"). Beaton later transformed her Twitter sketches into a finished strip, which is 100% worth reading.
