I thought that with the exception of one dress, they were all great.
Natalie's dress caught my eye the minute she came on screen, and this is no reflection on Natalie, as I'm sure she probably has no control over the design.
It looked like she'd come straight from the pool, with a very sheer sarong wrapped round her. I actually like my sarongs to be less revealing than the skirt, if you can call it that, of her dress was. I've seen women on time beach look more covered up.
She looked like they just ran out of either time or ideas when they got to her dress. It didn't come close to the quality of the others. Primark v designer dress difference. IMHO of course.
