Im 5’6, 130 pounds, wear size 4 to 6 pants, and wearing a size small here! This small feels true to size 🤗 I LIVED in this bathing suit last summer and just wore it all day today. I feel so fun every time I wear it! Material is a nice thick material, and is super comfortable. LTKSwim LTKFindsUnder50 LTKStyleTip
