Reviews

Love these!

"Love these. Love that they're 95% organic cotton, fit true to size, dont cut or dig into my waist, stay put, dont roll. The gusset moves a bit forward occasionally so it would be nice if it were a bit longer maybe? Also, I wish they came in more fun colors!"

— Beth F. (5/5)

Odd shape and weird placement for label.

"The material feels comfortable, although I couldn't wear them. The triangle is super long and narrow making for an odd shape, and the coverage is strange. The elastic is a little loose and seems like it will stretch easily so I'm not sure downsizing will help. THE LABEL is in the front and is extremely obtrusive - even when cut off, there are bits remaining. Whatever material the label is made of is very irritating."

Already came back to buy more!!

"My new favorite thongs! Love that they are organic cotton and feel like I’m wearing nothing. True to size. I’m normally a medium and purchased mediums. Athletic build 5’ 7” 140 lbs."

— Blair M. (5/5)

Fit

"I really like the minimalist structure! I could have gone a size smaller than I did."

— JS (5/5)

I love strings feel like

"I love strings feel like you don’t wear them, especially these with just that subtle ‘string’ in your waist. Important is the fit and support around your labias, and it does support them nicely. The only constructive feedback I have is that the fabric around the labias could be just a bit more thicker."

— Viv S. (4/5)

Perfect

"It fit so nice, no lines and comfortable. I sized up, usually a small got a medium. Glad they were all organic cotton."

— Desiree M. (5/5)
