Thanks both, via the Dress For Success suggestion I came across a charity called SmartWorks -
http://www.smartworks.org.uk/ who provide high quality interview clothes, styling advice and interview training to out-of-work women on low incomes.
In view of the fact that they only work with women I called them to see if they know of a similar charity doing the same for men and they suggested a charity called Suited and Booted -
www.suitedbootedcentre.org.uk
So I am going to organise sending my husbands clothes to them (and fish out a few of my own for SmartWorks!)
Just thought I'd let you all know in case you want to do the same.....
Many thanks for the suggestions.
