A side-tie brief replaces the elastic waistband at each hip with a pair of fabric ties that the wearer knots. The style is common in swimwear (Brazilian bikini bottoms) and in romantic or bridal lingerie where the ties serve as a visual feature.
Functionally, side-ties are adjustable — the wearer can tighten or loosen at each hip independently.
How to Identify
- Visible bow knots or fabric ties at each hip
- No elastic waistband at the sides
