It's the penultimate day of Bellatrix's 7 Day Challenge and we have one final lingerie set from the eco-focussed brand Knickerbox Planet. This time we've gone for white which is a colour that Bellatrix loves, it's this Knickerbox Planet Admirer cut-out detail recycled lace bralette and cut-out detail high waisted thong for her to review. Remember to come back tomorrow for the last day of Bellatrix’s 7 Day Challenge based around brands that are creating eco-friendly and sustainable products.

"The tag is also attached with just a piece of string rather than plastic which is good and the bag is also biodegradable." Bellatrix
