Don't be too hard on yourself it happens to all of us. There have been several threads devoted to this topic and there is no real agreement except most feel it should be tossed and not re donated. Not sure about how to authenticate the clothing.
Thanks for getting back to me Gail. I'm sure it has been hashed over a few times! I think I would just feel I hadn't wasted my money if it could go to something good like helping the designers know the copies that are out there. Throwing it in the bin just seems painful. Maybe I could make coasters out of the leather since it's actually good quality (I know a lot of fakes are terrible or not even real leather).
Anyhow this place is great because it really does provide a great service for buyers and newbs and also helps curb the fakes. Will keep looking to see if I can find something to do with the mens mulberry suit. Thanks again.
P.s I was wondering if theres anything that can be done about charity shops selling fakes? I have seen so so many fake designer goods in charity shop windows.
