Don't sell yourself short. Only asset? Please! While I fully accept you could look even better accentuating your waist, you are pretty stunning even without doing so
I was just thinking of body shape, though. I'm small, have short legs and wide hips but a big hip/waist difference, so basically, for women like me, a high waist is not very flattering.
Unless you're in a Jane Austen period movie (in that case, I have to say that curvy Jennifer Ehle looked a thousand times better than skinny Keira Knightley).
For women like Kim Sears, well, I'd say almost anything can be flattering. She seems to be of medium height, she's thin but not skinny. And she can wear high heels like this, when it hurts me just to look at the picture
