Our great friends over at the Corrie Wardrobe dept have helped us to track this one down.
Beverly's (aka Coronation Street's Liz McDonald's) jacket is a Star by Julien Macdonald Designer green tropical pansy print scuba jacket, available exclusively at Debenhams I think.
It Was £55.00. Then Reduced to £ 16.50 - unfortunately it's now sold out though. I suggest trying Ebay, or maybe try in store. At least now you know
