Frequently Asked Questions
Do they show under tight clothes?
The SmoothFit Thong, Bikini Brief and Full Brief are designed with seamless finishes and a bamboo viscose fabric that lies flat, reducing visible panty lines.
Will they roll or ride up?
Our Body Shorts waistband stays in place, and the anti-chafe panels help prevent riding up even during workouts.
What style of underwear should I choose?
Body Shorts: best for glide and chafe prevention, ideal under skirts or loose shorts.
SmoothFit Bikini Brief: a go-to style for daily wear, with moderate coverage.
SmoothFit Thong: your best bet for zero panty lines under tight or formal outfits.
SmoothFit Full Brief: fuller coverage in the same soft, breathable fabric.
