I'm 5'2" & 125 lbs. I ALWAYS wear a MEDIUM and most reviews said true to size, but these are BIG. I EVEN double checked tag to be sure it was a medium. I immediately washed them in SUPER HOT CYCLE and HIGH HEAT DRY. They are still pretty big, but did shrink ENOUGH to wear. Love poplin, bc it's breathable for Savannah's hot & humid temps. They were fairly stiff until I washed them, but that's what poplin does. They are comfy after some fabric softener and will continue to soften with each wash. I'll be keeping this pair, instead of returning for a small... mostly bc I'm hoping they will keep shrinking in hot water wash until they are perfect, then I'll wash in cold. If not, next time I will get the small. Oh, if you are short like me, you'll want to roll the waist band a couple times. Would recommend.
