It's my granddad's funeral tomorrow. I have no idea what to wear. I only own one dress and it's knitted and itchy and I'm worried I'll be too hot. Here's the question. I have smart black trousers and a shirt... Will that be appropriate? With heeled boots? I normally wear jeans and converse every day and every job interview I've had has been in the summer so I have nothing suitable to wear. Starting to panic.
