Demi Rose Mawby flashes major cleavage in dangerously low-cut black dress at London shop launch

Demi Rose Mawby was flashing some major cleavage when she stepped out in London on Wednesday night.

Never one to shy away from showing off her ample assets, the Instagram model slipped into a dangerously low-cut black dress for the Nasty Gal store launch in central London.

Demi, 22, risked spilling out of the black strappy design that also featured a deep thigh split.

She went accessory free and teamed the outfit simply with black heels and a small black clutch bag.

As well as flashing her assets, the model - who shared a raunchy video as she got ready for her night out - was also sporting a big grin when she stopped to pose for pictures outside the venue.

Other star guests at the bash included singer Ella Eyre who was the polar opposite in a huge light blue fake fur jacket and matching coloured trainers.

Ex On The Beach star Chloe Goodman, who has been keeping a low profile lately, also tried to hog the limelight by flashing her nipples under a sheer top that she paired with ripped jeans.

Chloe was joined by sisters Lauryn and Amelia who both played it a little more safe on the night.
