Karl over on his blog, tcritic.com, made a very interesting post recently showcasing various tshirt/fashion related Facebook applications.
Now I’m not a big Facebooker, but I didn’t realise that ONE such application existed, nevermind a dozen or more. Now some of them are fairly cool (Threadless Plus) wherease others are just, well, almost meaningless.
In terms of users, My Label has by far the most (241 daily active users).
Anyway, head over to tcritic to read the whole post.
