The 18-piece Future Heirlooms capsule fused Madhappy’s vintage-wash touch with Guest in Residence’s knit backbone.

Madhappy and Gigi Hadid’s Guest in Residence quietly stitched their viewpoints together this week, releasing an 18-piece women’s capsule collection titled “Future Heirlooms.”
Guest in Residence’s trusted knitwear formed the base; Madhappy ran its hand-stitch and vintage-wash signatures across waffle-knit hoodies and joggers, rib-knit polos and shorts, plus full-zip sweaters and cargo pants. The result was knitwear that looked lived-in from day one while keeping Guest in Residence’s tailored proportions intact.

The line was sold only on madhappy.com from Wednesday at noon Eastern, with prices spanning $150 to $275.
According to a spokesman, the two studios already shared friendships and a respect for construction and quality, so bringing them together “felt natural.” Madhappy said it would keep seeking projects with women-led labels through the year.

Campaign images, shot by Stevie Dance, featured Hadid herself—Guest in Residence’s founder and creative director—wearing the pieces against a clean studio backdrop. Away from the set, Madhappy continued to fund mental-health research and awareness through The Madhappy Foundation and its Local Optimist magazine, launched two years ago.
