This swimsuit design is super cute. I got a medium, I’m 5’5” and 140 lbs and the swim suit fits alright. It definitely fits like a thong. Your butt will be out. I’m not gonna post a pic of me wearing the swim suit but I provided a pic of one in a similar style that fits the same way as the Fendi swimsuit. There is some weird extra fabric under the left arm pit. I’m going to have to tailor it to fix it. Also if you wear this swim suit you’re going to have to be conscious of your pussy not falling out when you bend over or when you stand up from sitting. Also the fabric in the butt will be come loose when you stand up from sitting so you’ll have to fix it every time. Also I saw another review on how to wear it. Both straps go over the left shoulder. Like I said. Super cute design. Kinda disappointed on how it fits. I wish it was more secure.
