Delve into your mum or dad’s wardrobe and see if you can find one of these – an old Aran sweater. If you’re not in luck, the charity shops often get them in. While a baggy Aran may not be your style, with a hot wash, a sharp pair of scissors and a few simple crochet stitches, you can create a new top that’s unrecognisable from the old one. This one is so stylish and chic, it’s miles away from the old saggy sweater you started with.
