My Mum had them done about 23yrs ago. As far as I know she hasn't had any maintenance done?

What do they do to 'maintain' them?

I remember when I found out she had them done. I was about 17 and devastated, as I thought mine might eventually be her size!

I'm thinking about getting them done when I reach 40. Mine are on the small side, but not too saggy yet. I'm a C cup, but not a nice full one! I'd actually like some lipo on my neck first. A hereditary double chin happening here!
