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 4 we have Katie reviewing the Curvy Kate unwind high waist knickers in the colour mink. Come back tomorrow for more. Will Katie and Kelli have the same views and pick the same knickers after reviewing them all? Find out on Sunday. Filmed in 4K.

"You have a lovely elasticated band and some lovely detail here with the Curvy Kate tag which is a nice touch." Katie
