The reality TV stars flew to Dublin especially for the grand opening of Cathedral Bar, Grill and Smokehouse on Friday (12 June) - and both looked stunning in blue.
Former TOWIE star Sam chose to wear a light blue buttoned shirt, teamed with a tight denim pencil skirt - and we LOVE this look.
Wearing her 'bronde' hair loose and silky, 24-year-old Sam rocked casual glam to the MAX!
Older sis Billie, 25, looked gorge in a vibrant blue jumpsuit which flashed plenty of cleavage.
Looking tanned from her recent trip to Marbs, the mum-of-one wore her lightened hair up in a loose bun.
Former Coronation Street star Georgia May Foote also attended the launch night in the Emerald Isle.
It marked the first public appearance for her and actor boyfriend Sean Ward.
And, although they only confirmed their romance last month after meeting on the set of ITV soap Corrie, it's clear from the photos that they are pretty smitten!
Hollyoaks actress Jennifer Metcalfe was accompanied by her boyfriend, former Geordie Shore star Greg Lake.
The TV stars were all present to witness the launch of the new state-of-the-art garden bar and club housing huge tropical gardens with 250 different plant species and a 25-foot waterfall over two floors. W-O-W!
