How to lose weight as a woman with an apple body type?

So the title says it all. I've always had fantastic legs and arms. I'm overal rather petite and I enjoy that. However all the fat went to the stomach... I eat incredibly healthy and walk everyday for about 1h (at a jogging pace). But at this point I feel hopeless!

I know is a hard body type to lose weight (in fact any of them are when it comes to abdominal fat) but is there any tips? Anything I'm missing ?

I overal feel confortable in my body and my boyfriend also likes it so that's no issue. But I just would like to define my tummy a bit more so I could wear like a sexy tight dress.

Tips?
