But in practice, I just don't think we're ready for mfg.com. When I submitted spec sheets for Pixyworld's dresses & shorts last summer, the response I got was somewhat puzzling.
Of all the hundreds of suppliers (domestic and overseas) they had listed, the only bids I got were from China. I have nothing against China, but I had hoped to be able to compare with some domestic factories too. Furthermore, the bids were so widely varying that I had trouble believing that all the suppliers were understanding my designs. Language barriers are still a big factor, as much as we would like to think otherwise.
The most unfortunate part of the experience was feeling stalked for months afterwards. I kept getting phone call after phone call to solicit more business, until I finally stopped answering their calls.
I would say the idea is visionary. Perhaps someday the fashion industry can run like a well-oiled machine, with a co-ordinated bidding system, and with buyers and suppliers leaving helpful feedback for future clients.
But we're just not there yet.
