This week’s 7 Day Challenge kicks off with a thong/panty takeover as Kelli Smith shares the results of her recent online shopping spree at La Senza. Once a familiar sight on UK high streets, the brand is now an online destination for lingerie and everyday smalls. Over the next 7 days, Kelli will be trying out a selection of thongs and bikini briefs, starting with today’s first pick which are these La Senza Remix cotton thong panty. Come back each day to follow her journey and on Sunday she will reveal her favourite.

"The waistband is very stretchy and it does feel like a nice soft elastic." Kelli Smith
