Rook Form Germany: Unitard Built on Modal/Spandex 1x1 Rib Knit
Rook Form, based in Germany, needed a unitard that delivered recycled content traceability without moving away from a clean, commercial silhouette. The finished fabric was Modal/Spandex 1x1 Rib Knit.
Project brief and fabric selection
The fabric selected combines 1x1 Rib Knit (alternating face and reverse loops) with cellulosic fibre with elastane, giving soft drape and high comfort. Construction is alternating face and reverse loops at 220-260 GSM. The brief also asked for plus strong recovery. Each lot was checked against GRS transaction certificate before cutting began.
Construction and fit decisions
Pattern and construction were adjusted around the chosen fabric: seam placement moved away from high-friction areas, stitch density was matched to the elastane content, and the fit block was revised once the first wear trial showed the panel tension distribution. The development brief set the outcome as every lot shipped with GRS transaction certificates.
Dyeing and finishing approach
Finishing was limited to processes that support recycled content traceability. Soft handle came from construction rather than heavy softening, which keeps performance stable through repeated washing. Consistency between repeat lots mattered more to Rook Form than an isolated best result.
Measured results
Measured outcome: every lot shipped with GRS transaction certificates, verified by GRS transaction certificate. Size sets were checked after five home washes to confirm that dimensional change stayed inside the agreed tolerance before bulk release. Fabric Modal/Spandex 1x1 Rib Knit supplied the base behaviour for recycled content traceability.
Repeat order performance
The style moved to repeat orders after two seasons. Bulk fabric is now booked against a fixed recipe, with test reports issued per lot, and the 1x1 Rib Knit construction is used for additional colourways in the same programme. The Germany market requires documentation, so reports shipped with every lot.
