What to know about Isa Boulder

Hand-knitted, made largely to order

Pieces are hand-knitted and crocheted in small runs by artisans in Bali, produced mostly to order rather than held as stock, so irregularities are visible by design.

Swimwear roots, knitwear core

The label started with draped, lingerie-influenced swimwear, then shifted to mesh tops, garter leggings, cut-out dresses and bodysuits as its main output.

Body-contouring, not clean minimalism

Founded by CSM graduate Cecilia Basari with Yuli Suri, the cut is deliberately 'awkwardly sexy' — close to the body, with a Y2K edge — and menswear is a recent addition.

Brand facts

Isa Boulder is a Bali-based label founded by Cecilia "Lia" Basari, a Central Saint Martins graduate, with Yuli Suri. It began with draped, lingerie-influenced swimwear before knitwear became its core: hand-knitted and crocheted mesh tops, garter leggings, cut-out dresses and bodysuits made in small runs by local artisans, largely to order rather than held as stock. The aesthetic is body-contouring and deliberately "awkwardly sexy," with visible handmade irregularities. Stocked by SSENSE, Net-a-Porter and LN-CC, worn by Dua Lipa, Kim Kardashian and FKA twigs, and recently extended into menswear.
