Adorable bikini set from luxury Revolve brand Lisa Marie Fernandez! Top and bottom are both a size 3 which is a medium in this brand. I have listed as a medium for ease but please refer to brand size chart - I would say it runs on the smaller side of medium. Never worn, still has hang tag on. Does not have a liner and did not come with one - never worn by me besides to try on with underwear for 2 seconds. From a clean, smoke free home.
