She might have looked to die for in her royal blue cleavage-baring jumpsuit.

But Sam Faiers, 23, was not the only one whose curves turned heads on Saturday night.

Her older sister Billie, 24, looked equally fabulous and busty in a skin tight red dress, revealing her slim post-baby body only two months after giving birth to her first child Nelly.

The sisters went out together with friends including Georgia May Foote to celebrate The Wright Venue's fifth birthday party in Dublin, Ireland.

Sam, who was diagnosed with Crohn’s disease in February of this year, looked incredible in her skin tight outfit which clung to her body in all the right places.

She let the jumpsuit speak for itself without dressing it up with any jewellery, only sporting simple gold sandals revealing painted red toenails for an extra touch of glam.

Newly single, Sam recently split from her ex-boyfriend Joey Essex after a string of arguments in Marbella a couple of weeks ago.

The Sun revealed that Joey, 24, called time on the romance while celebrating Billie's engagement to Greg Shepherd on their sunshine break.

A source told the paper that Joey flew home after the rows, 'They are constantly bickering and falling out. It's not been pretty.

'But the last straw was in Marbella. The atmosphere between them wasn't healthy and Joey simply had enough. He just had to get away.'

It's not the first time the couple have run into difficulties. Joey proposed to Sam in Dubai during an episode of TOWIE last year but they broke up three months later.

Meanwhile, Billie - who recently admitted she was lucky because she hadn't put on too much weight while carrying Nelly, her first child with fiancée Greg Shepherd - opted for a tight bright red dress.

She also wore her platinum blonde hair in loose waves and teamed her dress with a gold watch, a bangle and strappy heels for a boost of height.

Speaking in an interview with new! magazine, Billie said: 'I was lucky because I only really put weight on my belly.

'I’m not quite back in my size eight jeans yet – I’ve still got a way to go – but I haven’t started doing any exercise yet. I think now’s the time.'

Though Billie wants to get back into her size eight jeans, she's happy putting motherhood first.

'Nelly is the most important thing. I want to look nice but everyone’s been so supportive. It helps me not to feel pressured,' the new mum explained.
