Tee is size small- fits perfectly for me. Probably my favorite thing I purchased as funny as it is 😅 Skirt is XS- I def needed a small. Full try on haul in stories. If you are even a little smaller through hips or height/ the XS may work Abercrombie, white tee, basic tee, casual outfit, tennis skirt, athletic skirt, Celine, Emily Ann Gemma
