Vonny Lang joins us all week for an eco-focused 7 Day Challenge. Shopping for sustainable lingerie can be an expensive commitment, so we set Vonny the task of finding seven eco-friendly pieces with a total spend of under £100. First up she gets to review some Lindex high briefs. Has she managed to stay within budget? Tune in throughout the week and find out on Sunday which item ended up being her favourite.

"The material is very stretchy and it feels so nice, I love high waisted items at the moment."
