Heidiwood by Heidi Montag
Heidi Montag's Heidiwood collection for Anchor Blue was exactly what you'd expect: tiny skimpy dresses with tacky details like metal ring inserts, too short shorts, and animal print tank tops. This painful collection was nothing more than anyone thought Montag could design, after watching her futile attempts to steal the spotlight time and time again. Note that I can't find images of the clothes worn by anyone other than Montag herself, which isn't a good sign.
Abbey Dawn by Avril Lavigne
I'm going to go out on a limb and say that once upon a time, Avril Lavigne was a (pretty) good artist. But that ship sailed, and even after it had sailed, she decided to design Abbey Dawn for Kohls, translating a trashy teen wannabe-punk aesthetic into clothes barely anyone wanted to wear.
Mblem by Mandy Moore
As much of a darling as Mandy Moore was in the 2000's, her clothing line was nothing notable and folded after less than three years. We can all just own up to the fact that as much as we wanted to like this line, it was just a bunch of overpriced t-shirts that could have been designed by anyone with two hands.
Lindsay Lohan for Ungaro
Why Ungaro chose to bring LiLo on as "creative advisor" in 2010, after she had long gone downhill is anyone's guess, and the collaboration very predictably flopped. While the brand had hoped that her work would infuse the line with more youth, her sequined heart nipple pasties and suit jacket combos didn't impress anyone.
The Kardashian Kollection has been selling at Sears for a couple of years now, and no one knows why anyone would buy into a cheap clothing line "designed" by the women who peddle designer goods and luxury wherever they go. It's mostly the same bodycon dresses with the occasional keyhole, leopard, and gold that you would expect, only without the quality of their personal wardrobes.
