Paying for it would really be adding insult to injury!
I think that presenters make the mistake of dressing for the mirror, rather than dressing for the camera. There is nothing wrong with having a little bit of extra weight around the middle, and you can't magic up height if you are shorter... and with Julia's recovery from her ankle injury, and previous foot problems, getting her into more attractive footwear is probably a bit of a challenge at present.
If I was advising her, I would recommend she went for full length maxi dresses in a darker colour, but with bold splashes of colour. I would keep my feet and legs covered while enforced to wear the necessary but ugly leg support.
I might even suggest one of the dreaded jumpsuits.
But I do believe she needs to size up more than she realises to make the products look their best... which, after all, is why the female presenters are urged to wear Q fashion in the first place.
I hope her recovery continues apace, and she can get back to not having to disguise support items, wearing fugly trainers and generally doing neither herself nor the clothing any favours. Julia and Debbie are both blessed with looking younger than their ages, and they just need to make sure they don't keep picking up clothing sizes that work in real life but come up as too tight/small on TV.
