Best boxer briefs for women hands down
Size: X-Large, Color: Dark Colors
I really adore these! The material is soft but good quality and not thin. They’re perfectly cut to flatter any body, and the stretchy waistband is thick but not to the point where it digs in your skin. I normally wear a size L and I sized up to an XL and I’m so happy with the fit. The brief style is so adorable and I give these a 10/10 for being the most comfortable underwear I own

Waited to review...
Size: Small, Color: Dark Colors
SO so hard to buy underwear online. I liked Hanes cotton boxer briefs. but they changed the fabric a few years ago. While I preferred the cotton feel of the old ones, I eventually had to move along and try something else. These wash very nicely--and I dry mine in the dryer with no shrinkage. They don't ride up which is awesome. I have had mine for months so I can fully recommend them now.

Updated 7/25
Size: XX-Large, Color: Dark Colors
Not too long, not too short in the bum where you have a wedgie allll day long. I've tried soooooo many brands (Amazon probably hates my guts) but I've been searching for months to find some long enough to go over that crease between your thigh and groin. Mine gets soooooo sweaty and then itchy so I needed something to cover and absorb. The larger recommended size settled into my stomach/belly button area and makes it looks like I have the hugest fupa ever! I But like several reviewers before me mentioned-you might as well toss the grey pair. Its like 1-2 sizes too small. Just the grey one! ALWAYS! So I knew to try it on so I wasn't shocked later! Wish they had and all black set (hint, hint), without that weird, bad fitting grey pair. Just get rid of that one! Update 1: they do run big. And yes, liners/pads DO stick. Thank goodness. Update 2: bought 2 sizes smaller than Amazon recommended. Tight when tried on, much better after washing. Very stretchy. Now it's wedgie problem. All day, all the time wedgie. Not good. No one gets that women have butt's that are bigger than the front. So yes, it goes just below my belly button, but the backside barely reaches to the bottom on my tail bone/start of the booty crack. So now my search moves to men's boxer briefs....
