When we went on a family holiday to a country where imports were non-existent and everyone was skint the guidebook said if you need to tip people don't give money give chewing gum, biros, makeup.
I remember we were in a toilet and my mum was putting some eyebrow pencil on and a woman came in and was really sort of begging her to give it to her.
I guess that when everything is a struggle and things that were once available aren't any more they become important / symbolic / luxurious? Plus women who are used to wearing makeup are going to struggle if they can't get hold of it - whether that's a good thing or not (clearly not IMO!) it's a fact isn't it.
On the sexist thing I found the comment from someone in power about women looking better in russian made lingerie than french lingerie far more sexist.
