Vonny Lang returns this week with a 7 Day Challenge centred around eco-friendly lingerie. With many sustainable brands commanding higher prices, we’ve challenged her to track down 7 items that together cost under £100. For Day 4 she's got this Vonny Lang Even&Odd active light support sports bra to add to the mix. Did she manage to stay within her limit? Watch along this week and see which of her finds takes the top spot come Sunday.

"OK, so we have some recycled nylon in this sports bra."
