Sainsbury' have a new delivery of the sport vests this week. At £5. each they are a bargain. Consist of two items sewn as one. A top vest and a 1/2 size one underneath. They have long straps which can be altered. Called Sport. Don't make the mistake of looking in the underwear dept. They were hanging in the normal top aisles today. Up to size 20. Well worth a look. I have mine on for shoppping today. Nice and comfy.Comes in Black or white, cheers Penny
