It's fine to express your dislike for something, Sewsusan, and several people have done that. But, they've done it in a constructive way that offers solid reasons for why they don't like the collection. It is bad form to write rude comments. Imagine how you would feel if someone said *your* work is 'fit for the dump.'
You have to think about the target market for your designs. My younger clients would love these looks, and even some of my 30-40 year-olds would like designs like the Mobius dress and the tie-dye tank and blue skirt. I've seen these construction techniques in some of the stores that target the 20-somethings. However, my older ladies would not like any of these designs, and, most of my clients of all ages come to me looking for more polished and tailored design pieces.
Threads, please keep showcasing a wide range of designers and styles. After all, if we all did the same thing, what's the point in doing it at all?
