You're slightly bigger than me, but I have the same body type as you. My waist/shoulders look tiny in comparison to my thighs/hips.
There's nothing you can do really. Like the person above me said, if you want to lose weight on your hips then you'll also have to lose weight all over, but if you have the same body type as mine (which you seem to) then the thigh to waist ratio would still stay quite large.
I persnally wouldn't/am not worried about it, because I think it looks fine and it also isn't unhealthy. In fact, people who accumulate more fat around their thighs rather than their abdomen have substantially lower risk of heart disease than other people (which is part of the reason why women live longer than men - they have more fat accumulation around their thighs to accommodate a potential baby).
