Size all the way up.. two sizes I ordered a small returned that and got a medium still didn’t fit I definitely needed a large. I’m usually not a large but because it has NO STRECH at allllll. Beautiful top though I’m sad the Large is out of stock. But yeah if you got a big back definitely size up twice lol

You have to order like two size up for it to probably fit. I'm a medium and order a large and it didn't fit me. Return it
