Trilogy (based in the UK) is a great place to find the latest European trends in designer clothing, denim, accessories and Trilogy Exclusives by 3 Brand, Hudson, Sara Berman, Mih, Pyrus and Chinti & Parker.
I also love the idea of a soft supple Summer Leather jacket in contrast to stark white jeans - this gorgeous number is by Helmut Lang while the jeans are by J Brand.
If you're in the UK, you can visit any of the five Trilogy stores (Chelsea, Marylebone, Kensington, Hampstead, Wimbledon) but if you're not, don't worry - Trilogy offers convenient international delivery :)
Be sure to check out another hot UK designer - Julian Hakes, Shoe Architect.
