A friend just told me about this amazing blog called DressInterest, and I think you guys will loveeee.
Basically, it compiles a ton of fashion pins on Pinterest in one spot. There are pages for accessories, dresses, occassion, feeling, etc. to separate the pins into the category you're looking for. Each pin even has a convenient "pin it" button to pin straight to your boards.
I've already added so much from this site to my Pinterest fashion board.
Take a look at the site and let me know what you think!
