Ok, so lately I have been wearing from a 37.5-38.5, not the usual 39-40. I have not gained(that much lol) nor lost any pounds...so I cant understand why in the world my CL sizing is off. I wore my Decolletes today, which are a 40 and they are slipping off. They are already broken in & ive worn them a million times. I just dont get it. Am I the only one???
