If you have no car then you need a warm coat in most countries in Northern Europe or the USA.This may cause you to faint in over-heated shops.So don’t go into big shops and get groceries on-line.Otherwise get a coat you can take off and fold up.It may have to be a dressing gown!My husband once went shopping in his for a dare.

If you choose the right fabric many clothes are wearable all the year round in theory
