Due to pregnancy weight gain I haven't really got a warm coat that fits well. I'd like to buy a second hand one from Vinted or charity shop without spending too much as I'm hoping to lose at least another stone in the next couple of months.
What brands should I be looking for? I've always bought fashion/high street but would rather buy something actually waterproof and warm this time. I'm too old to feel wet and cold for the sake of fashion!
