I'm a big fan of statement, patterned or coloured trousers for both summer and winter. I usually wear mine with a plain coloured top and fun jacket.
I recently wore these rose gold and navy lace printed Boden Party Trousers (now in the Sale) with my Nice Pear shoes (also from Boden but have sold out) a black top from H&M and velvet Topshop bomber jacket.
I wore this outfit to a Christmas dinner with friends but i would wear these trousers with a black polo neck and brogues for work or with a white t-shirt or sweatshirt and trainers for a casual lunch.
Here are some alternative statement trousers and variations of my outfit:
