This collection is all over the place. Bits of it (the red tartan dress, the navy kilt, the shoes, even the jumper) are ok but the materials are shoddy.
The Urban Outfitter tartan dress on another thread is cheaperand made of cotton. Lots of brands, e.g Nobody's Child, Joannie, Anthropologie, Seasalt and Palava can do pure cotton and linen dresses for the price Boden is asking for that dress, or less. Palava even make them in the UK.
The navy kilt would be fantastic in wool, even if it added another £100 or so.
