Skydiving coach Laura Muller from Yorkshire tests the new Belvia Bra by jumping out of a plane from 15,000 feet above Hibaldstow airfield. The 150mph challenge was designed to show the ability of the £12.99 underwear to give firm hold despite not having hooks, wires or adjusting straps. The new Bra is designed to rid the wearer of the "fat back" effect of traditional bras by not digging into skin and is available from ASDA, Boots and www.JMLdirect.com. Pretty Laura said "I was approached by JML to do the jump and I thought I would give it a try -- anything for a giggle. If a bra can stay comfortable at 150 mph, then it can certainly withstand a night out partying."
