Our third 7 Day Challenge this week comes from Luna who wanted to see if she could buy items for less than £2, including delivery! We thought it was not possible but she proved us wrong. So do you want to see what she's managed to purchase? So for day 3, Luna has chosen to try an unbranded stick on bra. We've tried lots of these invisible bras that are available on sites like Amazon and eBay. What will Luna make of her purchase today? Come and join us today to get the lowdown on the silicon strapless self-adhesive bra and remember to come back tomorrow for Day 4 of the Challenge and then at the end of the week Luna will be picking her favourite from all the items she gets to review this week.

"I was curious about this, I'm not going to lie. I have some invisible bras and I personally haven't found any that are particularly great." Luna
