I tried on a medium at it was hugeeeeeeee It is too big for anyone!!! I am 5' and a size 8/10.

**NOTE this sellers sizes are ALLL over the place - I get it - it's manufactured over seas - but I have multiple XS items from them, some S and some L. they ALLLL fit differently.  - also I bought this purple flow-y dress and its says online size XS - which is accurate but for a child!!! the tag literately says CHILD SMALL - beware returns are hard for this seller unless prime. but for the price the ones you like are more than worth it.***

This is the purple dress:
