I've always been a cotton only knickers kind of girl - but on a shopping spree back in the spring, I bought some Next microfibre bikini type panties - I liked the soft feel that I thought was softer than even cotton. I have got along fine with them and went to buy more on-line when I realised that they are 100% synthetic polyester! (as it seems are all microfibre undies). I had no problems through the hot weather even though I can be prone to thrush. I'm now a bit cautious - particularly if I start wearing with winter tights. How do others get on with microfibre - are they as good as cotton for down below health and well being?
