J.Crew and web-based stationer Paperless Post collaborated on a collection of cards and invites that "don't take themselves too seriously," and we are seriously smitten. The slightly snarky but utterly charming invitations and greeting cards are available in a variety of designs and colors and all feature the witty whimsy that we have come to expect from both the clothing designer and the stationery source. Available to send over the web or by snail mail, this collection has something for everyone and every occasion. Now, we'll just be getting back to planning the party we're only hosting so we can send out these invites. Paperless Post.
