She seems a little more upholstered than I'd find ideal and perhaps getting a bit of a belly and thicker at the waist but then again there are ladies I find attractive that others will find too skinny for their tastes.
As long as she's happy, then that's OK
Having said all of that, there are a LOT of fat people in the UK too. When I was a kid (about a billion years ago) there were a couple of "fat" kids in each class. These days more than half the kids appear to be overweight and there are some who are almost immobile. Likewise for adults, looking around the office I work in, I'd say that 75% of the predominantly male occupants are overweight.
