I purchased the navy skirt in 2XL because I didn't want to risk it being tight around my thighs. I needn't have been concerned and, in fact, the larger size means there is excess material around the waist (a little bulky, in fact). I went on to buy the same skirt in white in XL and it is a much better fit for me. I am size 16-18 (because of my bum and thighs, not my waist). I will be removing the draw string from the navy skirt to reduce the bulk.
