I have a summer jacket but it's from a sports shop, great for a showery day but not great if I want to dress a bit smarter with a nicer handbag. I'm also going on holiday somewhere warmer next year and would like a nice (inexpensive) summer jacket.
I've looked around and there doesn't seem to be anything! I definitely don't want denim as sometimes I'd be wearing it with jeans and double denim is not a good look.
