I often wonder how much of donated clothes actually gets to where they are supposed to. I am not just talking about bras but clothing generally. I live in Africa, but most definitely not in the poorest parts of our continent. We get a lot of 2nd hand clothing here, we even have a store than opens up in winter only which sells only winter coats that I am going to assume have been donated. It appears that they are from Europe as I recognised a lot of the name labels. The thing is, they are not donated on here, they are sold. You buy by weight and not per item. I suppose if you happen to find a pure wool coat it will be a bargain, but if its just a polyester one, then you could probably find one cheaper elsewhere new.
Also, the rag industry is very big here. A lot of clothing that comes in (I am not saying its from charities, but its coming from somewhere) is cut up and bagged up as rags for cleaning in the workplace. I sell these as part of my business and on the occasion I have kept a bag for myself, the labels are still on some parts of the cut up t-shirts (or whatever fabric rags you buy) and have been labels of Gap logos, Next etc. I do sometimes wonder if they are donated, and then if so, someone is making a quick buck from these goods.
There is the most terrible poverty in parts of Africa. My dh travels to those parts a lot for work. So, just so that I know that i have done my little bit and know that it gets to where it is meant to, on the flights that allow extra baggage (some flights you can take 2 x 20kg cases), then I pack up a whole suitcase with outgrown clothes, kids as well as adults that we no longer want, and dh hands them out to them when he gets there. We have been doing it for years now, and dh gets quite touched when he recognises one of dd's dresses that he remembers giving out years before, now being worn by yet another little girl.
So personally, I don't donate to charities collecting clothes, as I simply don't trust that they go to where they say they do. I am sure that some are, but how do you know what happens to the items as you bag them up and hand them over?
I do donate to a charity shop locally to us for rape victims. The things that they require are sanitary towels, new underwear, toiletries and that sort of thing. But I know that they are linked to the Rape Crisis Centre and they distribute these items where and when as needed.
