The blog Go Fug Yourself, allows garb critics to vent about "fugly" medieval and Renaissance costuming they have found online.
From the blog's introduction:
In tribute to Go Fug Yourself, we document the horrors of poorly-researched, poorly-made, or just plain fugly medieval and Renaissance costuming. We're limited to professionally made costumes, and no cheap Halloween products, unless something goes so far beyond taste and common sense that anyone should know better than to make or wear it.
A slightly racy (PG-13-ish) definition of the word "fugly" can be found on the Urban Dictionary website; see the link below.
