Compliment accepted, Fashintern. Though at the moment, my "back" could use a return to the gym.
Anne, I think the modifiers can be key among those who are more generally similar. So you, Angie, and I are all slim or straight hourglasses...but...we can't dress identically for flattery because...
Angie has a very long neck, short hair, a regular waist (neither long nor short), a short rise, and relatively longer legs than you and me. She also has long arms. She dresses to fill or flatter the neckline. She often aims to lengthen the leg line, also, unless going for a JFE look. She will emphasize or surrender the waist at her pleasure.
I have a slightly long neck (but not as long as Angie's), short hair, a slightly *short* waist, a *long* rise, and my legs are just slightly short in proportion to my overall height. In particular, my calves are proportionately short. I also have short arms. I'm 2 inches shorter than Angie yet my frame is overall a bit larger than hers and even at my lowest weight, I am less elegant looking and more compact. I dress to fill or flatter the neckline (but this is a lower priority/ need for me than for Angie, or rather, I have slightly more options for doing so). I almost always aim to lengthen the leg line. And I emphasize or surrender the waist at will.
Your general body type is similar to Angie's and to mine, but you have a regular length neck, long hair, a long waist and a long rise. You don't need to worry about filling in the neckline/ chest area as much in your dressing. And you have the perfect waist to highlight. This might be why you sometimes find it difficult/ counter-intuitive to surrender the waist -- even though you actually look great in that type of outfit, too.
The current high waists and wide crops l are absolutely made for you. Go for it!!!
