They are the joint owners of a clothing store so they really have no excuse for buying the wrong sizes when it comes to fashion.

The Only Way Is Essex stars Sam and Billie Faiers emerged in sunny Marbella, Spain, wearing some ill fitting swimming costumes, earlier today.

The sisters, who co-own Minnies Boutique in Essex, showed off their tanned bodies with varying degrees of success.

Bad choice: Sam and Billie Faiers both chose to wear some ill fitting bikinis as they sunbathed in Marbella, today

Sam, 21, stepped out make-up free and looked a little worse for wear as she moved slowly around the pool area.

She mix and matched her two piece bikini and wore a luminous orange pant with a bright pink top that had a rose detail on it.

Although the colours didn't clash too badly, the top was clearly too small for the blonde haired reality TV star and her cleavage was bursting over the sides.

In contrast, Billie, 22, looked great with a full face of foundation and mascara and a slightly better fitting green bikini top.

However, the well picked frilly design failed to give her 30H chest enough support and her cleavage seemed dangerously close to falling out.

The sisters were armed with glasses of water and a pack of Marlborough Lights cigarettes as they collapsed into their sun loungers.

All done: With their tans fully topped up for the day, the girls headed off, hopefully to put on some correctly sized clothes

The cast of TOWIE haven't wasted any time when it comes to doing what they do best – partying and sunbathing.

Despite being up all night partying in their beloved 'Marbs', Sam, Billie and Jessica Wright have been up bright and early this week catching some rays.

The trio flaunted their figures in sexy swimwear as they struggled through their hangovers at the Sala Beach Club.

Former glamour model Sam, 21, showed
off her deep tan in a multi-coloured string bikini, while her sister was a bit more covered up in a black kaftan.

Although
the cast make an annual pilgrimage to Marbella, this time they are
accompanied by the crew of the ITV2 show to film a one-off special The
Only Way Is Marbs.

No doubt
the complication of having heavy microphone batteries attached to their
swimwear for the outside filming would have been tricky for the cast.

So
despite their hangover, the women's sunbathing action – and no doubt
exchanging gossip from the previous night – was captured on camera as
they lay on their sunbeds.

The Only Way Is Marbs will air on ITV2 on Wednesday 13 June at 10pm.
