Well personally I think she looks great for having lost 5 stones!
Admittedly, those pics are pretty bad, the bikini doesn't do anything for her figure (she needs to be Gok'd lol!) and they seem a bit too light skintone, background etc.
Also, I don't know about anyone else, but whenever I'm having my photo taken I have to make sure I'm 'carrying' myself properly as I hate to see all the bulgy bits! So, I tend to straighten my spine and stand as tall as possible (which at my height of 4ft 11 isn't very tall!)
We can see that Fern wasn't expecting some pap to follow her on her holiday and start snapping unguarded piccies of her on the beach, she's trying to relax (trying to deal with all the flack of the last 2 months I suppose!) and enjoy her time with her family and this pap was probably half a mile away with n enormous zoom lens!
I really feel sorry for her and think she doesn't deserve all the aggravation she's had and I agree that her op was her business alone BUT I do think she should've stopped all the Ryvita adverts, maybe then people wouldn't have been so quick to damn her.
Sorry I've gone on a bit, but I'll finish with this, I still love seeing her on tv and I still think she's done fantastically well, everyone's weightloss journey is their own business isn't it?
