They've certainly come a long way since they won The X Factor a year ago.

And over the past few months, Little Mix have doing their best to forge a more mature image – going for sexier outfits and sophisticated hair and make-up.

On Tuesday night, the girls decided to go by the less is more approach as they showed off their slim figures in revealing outfits for the Attitude Awards.

Leaving Little (Mix) to the imagination: Jesy Nelson showed off her figure in a cut-out dress as she left the Attitude Awards alongside bandmate Jade Thirlwall in London on Tuesday night

Jesy was seen displaying her
newly-slender figure in a black mullet dress from MissGuided, with cut out sections on
the side, highlighting her tanned and toned stomach beneath.

The 21-year-old singer teamed the
outfit with a backcombed high ponytail, heavy eye make-up and nude
lipstick, finishing the ensemble off with a pair of metallic Kandee Shoes Dyna Booties.

However, Jesy did appear to be
slightly self-conscious in the outfit, holding her clutch bag over her
stomach as she made her way out of the event, hand-in-hand with bandmate
Jade Thirlwall.

Different styles: Jesy's mullet-style dress was long at the back, while Jade's minidress featured a cut-out detail

But Jesy had some competition in the revealing outfit stakes from fellow Little Mix singer Leigh-Anne Pinnock.

Leigh-Anne dressed to impress for the evening in an asymmetric black Gorgeous Couture dress with a thigh-high split.

And when Leigh-Anne carefully descended the stairs outside One Mayfair, she displayed perhaps slightly more than she intended to in the ensemble.

As the pretty singer attempted to
stabilise herself in her heel-less shoes, Leigh-Anne's dress fell even
more open at the side, revealing her toned legs.

All four members of Little Mix went all out on the glamour front for the evening.

Perrie Edwards opted for a slightly
more modest blue Gorgeous Couture dress, which complemented her dyed grey hair, while
Jade wore a cute sequinned minidress with a cut-out detail on the back.
