I thought katie looked really good when she was living with her 2 old friends in the gorgeous London house, i really dont like their current flat, yes it's big and apparently in a nice area ... but that's it. Anyway she looked at a healthy weight, her skin was clear, her hair washed and she wore her own style plus she was usually dressed in the day time.I think she should really ask herself if the content she's been spurting out lately is something she'd personally watch. Like, if one of YouTubers she follows, uploaded a vlog like one of hers, speaking in a baby voice/moaning about minute everyday things, would she watch and enjoy it?
If the answer is no, maybe she shouldn't be putting the content out to the world to see.
I think Katie's figure was similar when she was a little smaller, it's just that Katie is so tiny height-wise, any little weight she might have put on, will show more. Plus I suppose, if her sister practices belly dance every day, and the most exercise Katie had lately, was trying some old shoes on, Becky will have a nicer figure.
Looks wise, I think because Becky is more or less sticking with her natural hair colour, she looks more striking. I like that she is enhancing her curly hair as well. I think Katie's hair naturally has a nice wave to it and that if she tried using the right products, it could look really cool.
