I hope whatever the reason for JR's tummy seeming bigger isn't because of health issues and just unfortunate outfit choices. I imagine that if we met her in the flesh we would be shocked at how dainty she is. Cameras, age and ill health can be very cruel. The perception of JR's size would be massively improved by her wearing outfits together that don't cling faithfully to every lump and bump.
Same is true for all of us. Fitted? By all means. Clingy? Definitely not unless you have a model thin proportion. That said, I have total admiration for the body confidence of people who do their own thing, but that's not JR. She is very self conscious and aware when she looks awful, from my observations.
Julia, you are an attractive lady who has finally succumbed to middle age spread. Congratulations on keeping it at bay as long as you did, but now is the time to forget the dress size in the label and pick the outfit on the basis that it looks and feels just slightly looser. Please.
