I think these fit true to size, i like that they look better than i expected for a maternity panty. They are a tiny bit bigger in the back but with the slight shrinkage in the dryer they fit like a glove. They are very comfortable and the front sits just under the belly. I don't feel like a granny with these on, they are quite cute on! Glad i bought the 5 pack even though i didn't love all the colors the practicality was a win! Pre pregnancy i liked to buy M size panties because even thought im 55 and 118lbs i have wider hips and i don't like the waist to be super tight and these were no different, i think thats why the back was a bit loose but nothing that a little drying time couldn't fix.
