One of the names that crops up a lot is Gabicci. Their polo shirts are usually pretty distinctive and stylish, with contrasting patterns on the collar and front chest pocket or with button-down collars. They make a striking change to the (classic, but) usual Fred Perry single-colour styles.
Their proper website was down for a while, but it’s now open again.
And it’s a goldmine for anyone who’s got "too many" Fred Perry shirts.
