At The Costume Room, every piece begins with the fabric.
Quiet, honest materials chosen for their craftsmanship, longevity, and gentle relationship with the earth.
We work exclusively with natural fibres: sustainable materials that breathe, move, and age with a quiet grace.
All our materials are selected in small, intentional quantities from mills and makers who honour transparency, ethical production, and low-impact processes.
Our approach is simple: fewer fabrics, chosen deeply.
Every weave and texture is considered for how it feels on the skin, how it drapes, and how it lives in the wardrobe over time.
Nothing loud. Nothing rushed.
Just thoughtful, environmentally considered textiles, the foundation of pieces made to be kept, worn, and cherished.
OUR MATERIALS
100% PURE IRISH LINEN
100% Pure Irish Linen, exclusively woven for The Costume Room by Emblem Weavers, a family-run mill in Wexford, Ireland.
Naturally breathable, biodegradable, and renowned for its durability, rooted in centuries of Irish textile craftsmanship.
RAW ORGANIC INDIGO DENIM
Our Raw Organic Indigo Denim is made in Italy from 100% GOTS-certified organic cotton.
The cotton is grown using environmentally responsible methods, and the indigo is natural, extracted from the Indigofera tinctoria plant in India.
Every step uses REACH-approved substances, ensuring a safer, more sustainable dyeing and finishing standard.
GOTS (Global Organic Textile Standard): the leading standard for organic fibres.

Handwoven Donegal Tweed, exclusively handwoven for The Costume Room by master weaver Eddie Doherty in Ardara, County Donegal, Ireland.
Each length is created on a traditional handloom, preserving the depth, texture, and spirit of true Irish weaving heritage.
100% NATURAL WOOL WADDING
We use natural wool wadding for gentle insulation and structure.
Wool is naturally temperature-regulating, breathable, and biodegradable offering warmth without weight.
OUR COMMITMENT TO SUSTAINABLE FABRICS
All of our textiles are 100% natural, biodegradable, and ethically produced.
We choose organic, responsibly sourced materials not only for their comfort and beauty, but because they respect nature, skin, and working conditions.
