Jess has the same size chest as me (she mentioned it in a post) and I can say with some confidence that we don't comfortably fit into size 16 swimwear (tops) I'd look a right sight.
I'm 5'3 and I'd say she's the same size as me...and I'm a comfortable 18, at the high ends of the 14st bracket. Confidence is wonderful, but the bottom line is that ultimately we're overweight and our health will suffer for it. I'm not proud of my body. Am glad to have shifted 3.5st so far. I do have to admit that I feel like this body positivity movement is just a few bigger folks taking the easy way out. No one is truly happy being overweight/obese. Annoys me.
