We have 2 different size ranges depending on the style:
3 sizes: XS, M, and XL OR 5 sizes: XS, S, M, L, XL
If you tend to fit in between two sizes we do suggest to go with the smaller size. Our model is 5' 6" and is wearing size XS or size XS/S in our photos.
If you need any help figuring out your size please send us an email: firstname.lastname@example.org
