"Brought it to wear under the leggings but the seams can still show through the leggings."
"The bamboo T-string from CSB in size M fits well on a 25. 5 inch waist and feels very comfortable to wear throughout the day. The bamboo fabric is soft, breathable, and doesn’t leave any tight imprints on the skin. It does run a bit small, so sizing up is recommended if you prefer a more relaxed fit. A great everyday essential."
"Barely notice it’s there, no need to adjust!"
"Perfect seamless number"
"Love these. They feel like good quality, strong material and they have a glove like fit."
"These seamless T string are perfect to go under clothes or for the gym."
"Love it"
"Runs small and digs into sides making them unwearable. This was my first time ordering from this site so I reached out to customer service and they were no help. While I understand you can’t exchange underwear, I don’t understand losing customers for not providing resolution."
"Small sizes"
"Feels comfortable, can’t see lines underneath leggings. Style is comfortable."
