From curious to confident

The Matrioska is designed one-size with a generously relaxed, oversized cut that drapes naturally on a wide range of body types — the lace accents frame the silhouette so it reads feminine, never shapeless. On petite frames it falls more oversized; on curvier frames it sits closer to a relaxed fit. Check the flat measurements in the size guide to compare against something you own.

No — the lace is delicate and used as an accent along the silhouette, while the body of the tracksuit is soft, breathable cotton that sits gently against the skin. There are no harsh synthetics in the main fabric. If your skin is especially sensitive to trims, the lace placement means it rarely sits directly on irritation-prone areas.

Machine wash cold on a gentle cycle, ideally inside out or in a mesh bag to protect the lace detailing. Skip the bleach and hang to dry — high tumble-dry heat is what shortens the life of delicate trims. With this care, the cotton stays soft and the lace keeps its shape wash after wash.

Both — that's the idea. The lace details elevate it well beyond a basic tracksuit, so it works for city afternoons, coffee runs, and travel days, not just the couch. Wear the set together for a coordinated look, or split the pieces: the top over a slip dress, the bottoms with a fitted tee.

Quality cotton resists pilling and fading, and gentle washing keeps the lace crisp, so the set holds its shape and softness through regular wear. Like any piece with delicate trims, it rewards gentle care over hot, aggressive wash cycles. Treated well, it's an everyday staple with strong cost-per-wear — not a one-season buy.
