Well, nothing is ever certain until you try it on, but I wear and love drop-waist dresses because my torso needs lengthening and they seem to achieve that for me (and I'm not very hippy). That doesn't necessarily mean they won't work for you, but you might have to try harder to find a flattering style than I did.
You never know what you might discover. All these years I have been saying "NO TUCKING EVER" because I'm short-waisted and it just looked bad on me. But then I gave it another try this week and it didn't just work, it looked great.
In short: Some styles naturally work better on certain body types, but I think almost anything can be adapted for another body type if you're willing to put in the effort to find just the right piece. Just look at skinny jeans. They're a no-brainer for boyish, slender types...but anyone can wear them if they find the right cut and pair them with the right pieces.
