Hi, after months of chemotherapy and weeks of radiotherapy for breast cancer I have been left with horribly reactive and sun-sensitive skin. I have heat rash all over my neck, collar bone, and arm after this weekend, despite slapping on factor 50 (for super sensitive skin) 
It only calmed down (a little bit) since I covered up completely in one of DH's shirts with the collar buttoned and turned up and stopped with the sun cream. So I think I probably need some lovely cooling shirts I can cover up in.
Has anyone more stylish than me got any ideas what I could wear to cover up?
I don't want to spend anything over £50. I live in jeans on bottom half if that helps. Am at a loss what might cover me up but not either make me boil to death underneath or look really crap.
Any ideas?
