I have a lovely new crepe silk top which I bought for a wedding a couple of weeks ago. It was in the sale but was still the most I've ever paid for a top (£52) so I want to look after it. Problem is that it's a little snug under the arms and although I had it dry cleaned straight after wearing, it still pongs . Did I just pick a crap dry cleaner? Should I risk cold water handwashing it despite the label saying do not wash? It's bright pink and has fabric beads on it.
