Received these yesterday. Gray is significantly larger as you can see by photo. Black don't fit. Gray are stretchy and comfy but black don't have stretchy panel like gray.

These would've been great if they ran true to size. I really liked them but as you can see in my pic there is almost an inch difference in similar panties the same size. I didn't send these back because they were so nice n gave them to my roommate's 16yo daughter. I guess I will wait until they go on sale again in a larger size. I am 5' >140lbs. with an actual rear end n wear a size 4/6 in pants depending on cut. If this helps anyone.

One pair was sowed twisted, but they sent 5 new pairs so was worth the hassle of returning. Very comfortable wearing… i would buy again
