Andrea -- I can vouch for Not Perfect Linen. I have curtains and a pinafore from them, purchased several years ago, and more curtains, a midi skirt, and a tank top on the way for this summer. The quality of their linen is incredible (soft, drape-y, substantial, never stiff or scratchy), and they're a really nice group of people to work with. I highly, highly recommend placing an order!
Aida -- The Universal Standard jumpsuit looks fantastic. That line is full of cool stuff.
