All this week, Vonny Lang is on a mission to prove that sustainable lingerie doesn’t have to break the bank. Her eco-focused 7 Day Challenge comes with one clear rule... find 7 stylish and environmentally conscious pieces for less than £100 in total. Todays items are these Anna Field 3-pack briefs. Can she pull it off? Join us to see her discoveries and find out on Sunday which one tops her list.

"One of the materials in these briefs is recycled and that makes me happy."
