According to the AP website, size 3 is a 34C. I do not know if this size runs small or not, so please review all of the photos. Measured from strap end to strap end is 25"total.

Gold hook and eye clasp, gold hardware on adjustable neck strap, AP engraved on hardware.

Beautiful condition, looks new, most likely a past season item. Please ask questions if needed!
