I have a load of nice bras that are totally the wrong size (thanks MN for pointing that out here

I have weeded out the ones that look worn, but have about 10 that are good brands and have only been lightly worn, they look almost brand new.
Question is, if I put them on Ebay, am I going to get a load of strange people asking unsavoury questions?
I'd like to get some cash for them but if it means fielding questions from a load of pervs I'd rather hand them to the local charity shop.
Has anyone here had experience of this?
