I've tried soo many seamless undies and these first thing ones are FINALLY a pair that actually STAY IN PLACE and still don't show!!! Such an essential staple.

Actually perfect! Super light, super comfy, wash & dry quickly so perfect for travel. Waistband does not dig in so I’m buying more!

I’m obsessed with these seamless undies. They are so comfortable you feel like you are wearing nothing and unlike normal seamless undies, they don’t fall down or slip into unwanted places! Can’t recommend enough!! I ordered my normal size, they look like they run small but actually once you start wearing they are perfect.

I wore the underwear once and it was seamless but was huge on me after wearing for a day - seemingly stretched? Not ideal I am usually a 10 ish size - the M must be bigger than anticipated or the material stretchy..(sorry I really wanted to love them… :/)… would be open to trying an 8
