Leisurewear is clothes made for when you are relaxing or playing sport in a light way — soft trousers, hoodies, T-shirts, trainers. Shops and catalogues like the word; in everyday talk people more often say casual clothes, sportswear, or just 'something comfortable'. It is about ease, not about dressing up in your free time. Though actually it sits in a grey area: a running top might be leisurewear in a shop, and sportswear in another, and both can be right.
