This one-time Playboy Playmate of the Year has a really on again off again relationship with shirts and bras. In case that was too subtle -- we're saying she likes to take her shirt off, guys.

Claire Sinclair was named Playmate of the Year in 2011, and used that as a launching pad to pursue her dream career -- pinup star. So Sinclair took her act to Sin City and, from the looks of the photos, she's absolutely crushing it. Do all pin up chicks rock hand bras or that nipple tape 24/7? What have we been doing with our time?
