Perfect for us BBWs
Size: 3X-Large, Color: B002
I love the feel of these underwear. They are true to fit as well. I am 340lbs and bought size 3xl. They are comfortable and not tight in the legs.

Nice for the price
Size: Medium, Color: B004
I really like the LALESTE Women’s Boyshort Underwear overall!
They’re super comfortable, soft, and have great full coverage—perfect for everyday wear. The material feels stretchy and smooth, and they stay in place without digging in or riding up. Definitely a solid option if you like a more covered, secure fit.
My only downside is that they are a bit too high-rise for my personal preference. They come up higher than I expected, so if you prefer a lower-rise fit, just keep that in mind.
Other than that, the quality and comfort are great, and I still find myself reaching for them often!

Soft but easily rolls down
Size: X-Large, Color: B004
Comfortable and soft but it kept sliding down, I have a longer torso so that could be why, but I couldn’t get it to stay up, it would constantly roll into my C-section scar
