I have to get a bus into town so it will be boiling! I don't want to arrive a hideous sweaty mess (I tend to sweat when I'm nervous as well). I have a pretty limited wardrobe and can't really afford to buy anything else. I take it sandals would be a no-no? I have a subtly patterned knee length dress and a smart black fitted coat but I'm wondering what to wear on my legs/feet? Would bare legs be bad? I have flat pink pointed ballet pumps? Would that be ok? Thanks for any help!!
