Can you believe we're already on Day 6 of Shannon Crystal's 7 Day Challenge? Our gorgeous Shannon Crystal has been busy slipping into bras from a whole range of brands this week, discovering what works, what doesn't and which designs really deserve a little extra attention. Today, she's reviewing a Knickerbox plunge non-padded underwired mesh bra and with Sunday's big reveal just around the corner, could this be a last-minute contender for her favourite? You'll have to join us to see what she thinks! Filmed in 4K.

"I already love the colour, it's so vibrant. The colour is everything and I don't have anything in this colour, I love it!" Shannon Crystal
