If it's your jawline that's bothering you, it might well be worth having a go at facial exercises. I know they get rubbished by all the face-cream and cosmetic-surgery people BUT I met and gawped at people who've made a huge difference to their jawline and chin this way. One key exercise is to stick your lower jaw forward, clamp your lower teeth over your upper lip, then push your tongue strongly forward against the bottom of your lower teeth (you'll feel this in the muscles under your chin) and hold for five seconds, and repeat a few times.
