i ordered an xl because the material didnt look stretchy, and since its notorious for running small in size i ordered an xl to be safe. the skirt fit perfect, but the shirt is tight around the arms. im 5'2 and have thick thighs and thicker arms. your safest bet is to go up a size ( speaking mainly for the thicker or mid size girlies ) if you want to be comfortable

the skirt fits true to size but the top was a large and fits like a small/ medium!! it ripped as soon as i put it on along the seams
