i ordered a size Small and I''m 5''2 average weight (not too skinny, not too big, well proportioned but with a big butt). at first i didn''t like them b/c of the material, i''m one of those people who usually rather feel comfortable than look good, so i was hoping they were cotton style, but i got used to it. i use them in yoga and everyday. just as a warning, they are kind of slippery if you wear a tight long shirt, but i wasn''t too finicky about it, they''re comfy and look nice. so its a step up from not caring if i look good.
