Comfy cute boyshorts
Color: Multicolor-4pack-a1, Size: Medium
The boyshorts are so comfy,true to size & good support. The waistband doesn't curl,has a no show look & is good for Everyday wear. The colors are nice, doesn't fade in wash or shrink in the dryer. The material feels good & is lightweight. I highly recommend trying these boyshorts at the reasonable price.

Not all cotton panty.
Color: Multicolor-4pack-a1, Size: Large, Color: Multicolor-4pack-a1, Size: Large
These are comfortable. I weight 150 lbs normally I wear a size large. I ordered large. They fit good because they stretch. They are not tight, just comfy. I think if I ordered an X-lg they would feel more like my regular panties. Giving me a little more room. Also…I was under the impression that they mostly made with cotton. The crotch is the only thing that’s 100% cotton. I’ve attached a photo of the material content. I’ll be looking for another boxer brand that is all cotton.

10/10
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❣️
