To The Maxi: Lisa Snowdon Launches New M&Amp;S Campaign

Lisa gives back with M&S. Empics Entertainment

M&S face Lisa Snowdon is motivating shoppers to give as much as they receive (or rather, buy themselves).

The model was on hand to launch a new M&S campaign which encourages shoppers to save money on this season's fashions by donating clothes to Oxfam.

To kick off the initiative, Snowdon was ready for spring in a flowing printed maxi-dress, denim jacket and flat sandals. She also sported two Twiggy M&S tote bags, stuffed full of clothes.

Time for some spring cleaning!
