I feel like I could have ordered up a size.  I wear an 8/XL panty and ordered the XL in these.  They are great for wearing under skirts.  The skirt didn't cling to the material.  I always prefer cotton but you can't use cotton under dresses unless you also wear a slip and I can't have that many layers in South FL!.  This prevents thigh rub.  The waist band was a little tight but the design doesn't cause it to feel like it's gouging into your flesh but I probably could have sized up and it would have been even more comfy. The thigh part did not feel too tight. The blue color is cute and, for me, I like it better than a flesh tone.
