I've found a couple of new websites recently that Im loving!
The last one is a favorite of Daisy Lowe! They have such amazing clothes that are versatile and funky. They carry Wildfox (who do amazing tee's, seen on Beyonce and Cheryl Cole) and they also have vintage sections for all you ladies who love one off pieces! They are a little higher priced that what I would usually pay, but these are items you will be able to wear over and over again and mix and match with different pieces so its totally worth it!
Check them out ;)
