the legs and waist edges are wonderful. The fit seems true. The fabric soft & is not a light weight flimsy cotton. BUT what, WHAT is wrong with the majority of manufacturers of ladies underwear that produce panties that not only have thick side seams that stick into you (they could be soft & folded) but the inside crotch seams are open on one end...did I miss the secret purpose of an open ended seam in a "delicate" area ? yes let's all wonder why any woman would want a scratchy mobile seam rubbing against her crotch all day...and if you think that turning them inside out would help them you;re wrong, because them you have a flappy seam on the other side, only slightly less irritating AND if you wear pants, the flappy seam will catch on the inside of your pant seam, causing alot of panty shifting. My kindest thought would be : the seam was meant to be folded under and sewn down. as is the other end of the "flap" but the information did not translate to the foreign workers who do the actual  assembly & sewing..and no one at Hanes ever bothered the check...the ladies at Hanes must not wear their own panties..if they did, someone would have changed the design or taken their assemblers to task!
So, what uses could the flap be for :
1) it's kinda like a pocket...so you could put your feminine pad IN them. messy but they might stay put better
2) keeping your extra bills that don't fit in your wallet...except with all that movement going on down there, don't be surprised if you leave a trail of $ as the bills drop down & out
