W knows how to fit us biggies
Color: Black - Set 3, Size: 7X-Large
wirarpa is the only company that makes honest to goodness full coverage briefs...I have the boy short biker length ones and now these......They have a wonderful wide top of panty , no digging in because it's wide, always comfy
Wirarpa knows that women who are large/ fat etc have bellies and these are as close as you will get to feeling like you wearing nice panties .....no dig into crotch where panties meet thigh......
no more hurt skin from sitting down , these don't dig in
Pricey but I have wasted lots of money before searching. so I buy enough and have a good supply, you never know when prices will keep climbing Soft, no seams, wash in washer & hang on line/hangers to dry, never put in dryer
Biker length ones I wear around the house when alone ................
Only complaint: not all styles in my 5X size, you miss out on other styles but these two : panties and long boxer are my staples....... a company that KNOWS how to make decent big woman undies should offer all styles

Excellent Value
Color: Black - Set 3, Size: 5X-Large
I love these briefs! They fit perfectly according to the size chart, and are extremely soft and comfortable yet also help firm you just a bit. The crouch is large enough that a pad fits without hanging over the sides. They are also well-made and an excellent value. I cannot speak to durability yet, but I cannot see why they would not last. I will definitely be buying more!

this is my go to when needing new underwear.
Size: 3X-Large, Color: Black/Navy/Dark Purple/Red
Love these boyshorts for women. They're so comfortable, no crawling and breathable. I recommend for plus size women who has legs rubbing together causing irritation. Nice price as well. This is my go to when needing new underwear.
