Una (31) dressed down in some seriously skinny dark denim jeans, a purple top and a gold necklace.
Frankie (23) flaunted her figure in a tight-fitting leopard print dress with black sandals. Mum-to-be Rochelle (23) was glowing in a teal jersey dress and T-Bar shoes. Mollie (25) went for a deep pink cut-out dress and wore her locks down.
Vanessa (23) went for a more alternative look and teamed a graphic print pencil skirt with a cobalt blue blouse and a bowler hat.
