For this year:
Rachel is I think incredibly pretty, she has a lovely, innocent quality about her.
Sophie has such a beautiful but unusual face that draws you to her.
Fiona is very attractive, given her advanced years. She still has a lovely smile. I just wish she'd change her hairstyle - it's been described as a 'helmet head' and I think she'd look even prettier if she'd soften it a bit.
Natalie is very stunning looking, and I just love her hair, it's incredible (though poor Artem if it keeps whipping into his face ... I'd just HATE that) but she has strange eyes which spoils her look somewhat (one of her eyes seems much bigger than the other one).
Abby is obviously attractive, but for me her face is a bit too thin, and her ears stick out. Amazing eyes though.
I would have said Flavia for the most attractive pro, or Katya, but they're not in it this year, so I'm struggling. Maybe Iveta? She has incredible bone structure and has that wonderful Russian look about her.
edited to add: my OH, who is forced to watch this, thinks Darcey is one of the most beautiful women ever. He's said that if we ever split up she'd be his second choice, lol.
