Color: Multicolor-4pack-a1, Size: Small
These are some of my favorite underwear. I find myself reaching for these constantly. They're very good quality and very stretchy. I'm 140 5'3 and I got a small they fit great. Someone larger or smaller would fit in the small too. I do stress that the leg holes are a bit tight on my thighs and I don't have thick thighs at all. On someone with thicker thighs I'd say size up to a medium. You can wear these as mid/high waisted or low waisted. They're versatile! The cotton gusset is a plus too❣️

Better than Haynes at for less money
Color: Multicolor-4pack-a1, Size: XX-Large
I am surprised by the quality of these knickers. They are better than Haynes for less money and when I say they’re better, I mean far better, but I can’t believe how comfortable and STRETCHY best underwear is

love love love!!
Color: Multicolor-4pack-a1, Size: Medium
like my daily driver now, like i never thought underwear could be this good untill now! have bought 2 4packd and will probably get more in the future :) they are snug but not suffocating, with my darker skin i was worried of them getting darker in that area but so far(3-4 months) they’ve been holding up well and clean easily in the washing with a bit of stain remover!

Satisfactory
Color: Multicolor-4pack-a1, Size: X-Large
If your wanting an easy on high waisted underwear these work.
They are honestly strange material, a mix of three different things- not bad but different.
Not seamless, might ride up, slightly on the thicker side. Will last a while. Comfortable enough but not amazing.
Got for after a surgery and needed something different- these worked but would I get on a normal day probably not.

Super soft and comfortable!
I haven't bought new underwear in forever. I used to wear thongs, but now find them incredibly uncomfortable. The last few times I've tried to buy new underwear, the sizing was either way off (I'm a medium, but gave up after having to return them for a large and then extra large) or the quality was horrible (two brands stretch waaaay out and they can fall down while wearing them (I have larger ass-ets, so they shouldn't start to slide down during use). I tried these after buying some bamboo pyjamas and I love them! They are incredibly soft, comfortable, and stretchy. I can use them all day, and they work well, whether I'm lounging on the couch or wearing them under my spandex shorts at the gym, they don't ride up or slide down. They are both comfortable and look sexy, while providing support in all the right places. I haven't had them too long, so I can't speak on the durability, but they appear to be of good quality and I plan to order more, this time without the band.
