I’m 5’5 300 lbs, normally wear a 3xl or a size 24 in pants. I think the sizing runs a little small, the fabric does stretch a lot but it was made fairly small. The bikini area is also cut verrrrry high so if you got a chunky lower tummy, it’s gonna look a little weird. Wasn’t super flattering in that area, but with a skirt or pants over it, no one will see that, and it looks very cute! The arms are a little tight, especially when lifting your arms up, it kind of pulls the entire garment up with it? I will definitely wear it, but would suggest a size up.
