Reviews

super comfy but runs small

"quality and comfiness of the classic underpants are amazing- I've been wearing them for years and years and still have some of my first pairs - but I find that they run small. According to the size chart I should be a medium based on hip measurement - medium is definitely too tight for me! I size up to a large now and fit is much comfier"

Sheralyn F. (4/5)

Comfy, cool and I love them but…. . .

"…the waistband could be a bit more elasticy. Seemed droopy and not very stretchy thus not as snug as I’d like. I’d still buy them again but the waistband could use more whatever it is that keeps them snug. I feel like once the fabric is stretched at all it doesn’t return to it’s original shape if that makes sense(?)"

Sara G. (4/5)

Nice fit!

"My favorite try so far! I am 5’8” and weight 235 lbs, if I would have followed the size chart, I would have bought a 3XL. I opted for a 2XL based on the photos of the models, and it fits right for me. It has a lower waist line than what I currently wear and I was afraid it would roll down, but it stayed in place all day. The only riding up I experienced was during the night, the back side tend to bunch up where-the-sun-never-shines 😉, but during the day, they are very comfortable."

Improvements

"I ordered this style before and was hesitant to order again but when the offer of buy 3 get the fourth free I decided to take a chance. I love the improvement smooth fabric and comfort. I believe I got all of the colors."

Alana C. (5/5)

The perfect everyday pair!

"I just keep coming back for more! I now own the full collection of colours available in the standard bikini knickers - unbelievably comfortable, wash well, fit perfectly, I can't praise them more highly, the PERFECT everyday pair - I have replaced everything else I own with these, love, love, LOVE!"

Divine colour

"I only shop at Boody for all my underwear as the fabric is so soft & comfortable & stays right where it’s put! No riding up, no elastics digging in…. . pure comfort"

Terry P. (5/5)

Comfy, but. . .

"These are very soft and comfortable underwear. However, if like me, you have a short torso and a belly, then they're the wrong shape for you. Unfortunately, when I move, I have to readjust quite often as they slip down, roll or move out of place. My pair of full briefs, which came in the package I bought, is mush more suitable for my and my ahape. Love the fabric and the colour though."

Lizzie T. (3/5)

Finally, some comfortable underwear!

"This is by far the comfiest brand of underwear I’ve ever come across. Perfect for everyday wear, and I’m no longer constantly readjusting myself. I’m now slowly converting my whole underwear drawer to Boody!"

Elodie M. (5/5)
