I own quite a few Jack Wills items which include a coat, underwear/nightwear and general casual wear.
All items I have have worn well and the quality is really good. I have a pair of pjamas which are now at least 3 years old and are still going well. Similarly my wool coat is also 4 years old and is wearing well too.
Discount codes do frequently pop up, including student discounts which can help to bring costs down. Free delivery is often available over a certain spend too and generally delivery times are acceptable.
When I had an issue with sizing of an item, returns were easy and customer service was generally good.
If you are lucky enough to live near a McArthur Glen outlet in Cheshire Oaks there is a Jack Wills store there too.
