When Little Mix first burst on to the scene in their neon nu rave inspired hot pants, crop tops and edgy studded style we loved it, but we never thought we'd see the day that we'd be coveting their grown-up glamorous evening looks. That was until the girls stepped out on Thursday night for Leigh-Anne Pinnock's birthday party. The birthday girl herself opted for a strapless lace dress with a sweetheart neckline and body-con bodice design that really emphasised her curves. Teamed with a silver diamanté clutch bag, drop earrings and a statement red lip Leigh-Anne showed how the lady of the hour should dress LBD-style. Jade Thirlwall went for a more understated but luxe look with a a subtly embellished black dip-hem dress and colour-pop red court shoes. Whilst Perrie Edwards made Hollywood glam look easy in a vintage-esque embellished dress with short sleeves. The floor-length evening gown elongated the already leggy singer's frame and worked beautifully with her simple black clutch bag and purple-grey hair. But the Little Mix-er we're all talking about at Team LBD is Jesy Nelson who showed off her new svelte figure in a look-at-me low-cut, cut-out black dress in a eye-catching glitter fabric. The sexy maxi dress also featured a rather risque thigh-high split which we could only dream of pulling off. The statement making singer finished her outfit with bright purple spiked stilettos and ornate jewelled earrings. We love!
