ABOUT
The Costume Room is an independent Irish designer label creating gender-neutral pieces defined by sculptural form, quiet tailoring and a commitment to thoughtful, design-led craft.
Founded by Irish designer Sinéad Roberts, the studio creates pieces that are bold yet understated, contemporary yet timeless, designed for individuals who value quality, creativity and considered design.
DESIGN GROUNDED IN SLOW FASHION
The Costume Room is part of the slow-fashion movement in Ireland, creating pieces with intention, defined by complex yet quiet tailoring. Each piece is designed by Sinéad Roberts and made individually in The Costume Room’s Dublin studio, allowing Sinéad to reduce waste, honour the materials and work in a way that feels thoughtful and true to her studio practice.
Production takes place at studio scale and remains closely aligned with demand, helping to limit overproduction and excess stock.
The Costume Room designs for individuals who seek stand-alone original design with minimal effort and maximum ease. The approach blends sculptural silhouettes with a calm, considered aesthetic, creating pieces that welcome self-definition and move quietly beyond traditional norms, designed to be worn by anyone.
CRAFT + MATERIALS
The work is shaped by materials chosen for their integrity and character. The Costume Room favours 100% Pure Irish Linen, woven exclusively for the label by Emblem Weavers in Wexford; Raw Organic Indigo Denim crafted in Italy; Handwoven Donegal Tweed, woven exclusively for the label by master weaver Eddie Doherty in Ardara, County Donegal; and Natural Wool Wadding used for warmth and sculptural form.
Materials are selected with close attention to their origin, composition, performance and the form they create.
Further detail on the materials used across the collections can be found on OUR FABRICS, with more on the studio’s approach outlined in STUDIO PRACTICE.
VALUES
The Costume Room’s values are rooted in integrity, honesty and design-led craft. The studio works slowly, creating pieces with purpose rather than pace. Working at studio scale helps to avoid unnecessary waste, honour the materials and keep the making process thoughtful and true to The Costume Room’s studio practice.
The Costume Room believes in creating pieces designed to be worn often and kept over time, pieces that feel considered and pieces that offer a quieter, more thoughtful relationship with what we wear.
Every decision, from the fabrics chosen to the way each piece is constructed, is guided by a commitment to quality, responsibility and respect for the world we live in.
STUDIO PRACTICE
Pieces are made individually in The Costume Room’s Dublin studio. Depending on the piece and current studio production, it may be available to purchase immediately, offered through a waitlist or not currently in production.
Studio updates are shared by email, including news of new work and returning pieces.
