Six seams come together between your vag and rear exit. Not good.
I thought these were cute and liked the colors. They were on sale. I was looking for regular cotton boy shorts for women. I am very petite. For some reason it has become very difficult to find regular cotton boy shorts that have a gusset and the elastic band is covered. I do mean that I was just looking for basic cotton slip shorts that I have bought within the last year that have a covered waistband because I get irritation from elastic. Because of the weird data silos that Walmart and other retailers are now using, my purchase history will not pull up underwear purchases in the last year so that I may be able to reorder the ones I liked. I am so frustrated by this but needed to buy more underwear. I saw that the elastic was not covered but thought I'd try them anyway at the sale price because this elastic band is the type that can be folded over if irritation occurs. However, this is the worst fit of underwear I've put on in a while. They are made for a woman with large thighs or rear. There is a gap at the leg holes giving the feeling of breeze/no security at the butt and there is nothing, no tension there, to stop these underwear from going right up and what makes it worse is they must have made these for a woman with orifices right at the front of her pelvis. When you look straight down into the underwear you will see where the crotch gusset ends and the back seam begins. It is straight down! In other words the gusset ends and the left to right leg seam plus the seam going to the back ALL meet at this intersection which is right on top of my back door opening. This problem plus the fact that the leg holes are too big and nothing is holding the underwear down snug around my thighs means the most uncomfortable underwear seam JUNCTION is also going to be riding up my backside. I hate them. Cute colors but these underwear are not for people like myself who I thought was pretty normal despite being petite. I just hate them and I find it really frustrating that I'm going to have to end up sewing my own underwear, which is is a very basic style of underwear, not because they are no longer being made but because Google searches and Amazon searches are so confabulated and leveraged that I can't find them no matter how hard I try. I'm sick of this. I'm absolutely sick of this and UNDERWEAR IS IMPORTANT. I give two stars because they colors are really cute but I hate them and need to put an extra gusset in and try to take up the leg holes.

Great quality!
My wife loves these panties. She says they fit great, they are very soft and comfortable, and best of all they hold up very well when machine washing and drying. Now that she's put them to the test, I just ordered her more.

Comfy but wear quickly
Size: Large, Color: Organic Cotton 2 (5 Black)
These are perfect for every-day wear and i find them super comfortable. Mine are starting to tear and fall apart, which is more quickly than my other underwear, but I think its worth it for the price and comfortableness. I'll just replace them or repair them :)
