I'm going to a wedding in Spain at the end of May and need to sort out what I'll wear. It's not so much choosing an outfit that is my problem, as what to do about tights. I won't wear a dress or skirt without tights but I'm allergic to nylon, and to other synthetics to various degrees. I've got away with wearing tights for a few hours at a time here in England, but I'm afraid that in Spain I'll be hotter and sweatier, and will probably be wearign them all day, and so be more likely to have a reaction.
Are there any alternatives to synthetic tights? Do silk tights still exist - and would they break the bank?
