As we are taking a look at undies this week, we bring you a special long distance 7 Day Challenge duet featuring Katie and Kelli Smith. We feel that the Bridget Jones films have given big pants a bad reputation and we wanted to fix that. So each day our presenters will be reviewing big knickers. For Day 1 we also have Kelli Smith reviewing the same ASOS Betty logo cotton soft high-waist knickers as Katie has done today. Come back tomorrow for more. Will Kelli and Katie have the same views and pick the same knickers after reviewing the same ones this week? Find out on Sunday.

"They do look comfortable and they feel like very soft material and I think I'm falling in love with them already!" Kelli Smith
