One of my favorite brands from the USA is Free People. Although their price point is slightly higher than what I would normally spend, they often offer great sales and of course inspiration as well for searching for vintage finds, as their vibe is very bohemian and laid back.
Exciting news, Free People is now shipping to Spain and other European locations-hooray!!! Here are a couple of my favorite dresses from the spring collection! You can see more on the Free People Website.
