I say it's your body, so you make it suit you!
I myself haven't had plastic surgery, but I did have some knarly varicose veins stripped out of my left leg because they were getting so big and bumpy that I was embarassed to wear shorts or a skirt
I have fantasized about getting my boobs raised
a bit because when you have size 42D breasts, they are quite the burden! Well, raised and reduced!
Though I'm hoping losing weight and tightening muscles above them will do the trick.
My other "some day" thing is wishing I had a clearer jawline. I hate having my chin just kinda rise off my neck with a triangle of flesh underneath it! It's not a "double chin", it's just squishy.
It's funny the things I focus on when here I am at 200+ pounds, and I'm all weird about my JAWLINE.
Anyway - I say best wishes and good luck! If it improves your confidence and makes you happier in your body, what the hey!
