Reformation appreciates the importance of a beautifully cut dress. One such example is this emerald-green Maren dress, a slim-fitting piece that accentuates all the right places. Featuring a high neck, cap sleeves, a rear keyhole detail, a fitted silhouette, a cut-out back, a concealed rear zip fastening, an over-the-knee length and a back slit at the hem.

It uses eco-friendly materials in its products, renewable energy for its supply chain, and reuses all its textile offcuts. It traces most of its supply chain to ensure good labour standards and visits suppliers regularly.
