I found these jeans to be more fitted than slouchy. 
for reference, i'm 5'4" and 160#. i'm heavier thru the hips and thighs and ordered both the 31 & 32 petite (i usually take 32 p in pilcro) and the 32 fit well but was by no means slouchy. however, still very flattering and unique. i had purchased the other pilcro em in 32 p and they did fit looser and i would also recommend that style. always count on pilcro for great fit and style.
