Stumbled across this little site full of fun retro-inspired clothing today: http://www.modcloth.com/
Here's a few gems I pulled from their site:
Temporary Secretary Dress in Summer
Opera House Dress
Making Me Blush Skirt
Study Lounge Cardigan
Roll Call Blouse
French Toast Top
Cherry Cordial Flat
Brisé Ballet Flat
Lemon Meringue Heel
Haute Coco Heel
Loads more fun things on the website, and even some household goods. These were just some of the ones that jumped out at me. Super cute stuff.
They have a section featuring some actual vintage items, too.
