As someone with a long rise, long torso, shorter legs, shoulders slightly broader than my hips (my hip measurement is all in my bum, not the width of my hip bones, and my widest point is the top of my thighs vs hip shelf), and a slim waist, the most traditionally figure balancing look I can wear is a fitted top tucked into a full skirt that hits at my natural waist (and is fitted there) and ends around knee length. The fullness of the skirt makes my hips & shoulders look equal and exaggerates my waist's size by comparison, moving me more towards the hourglass 'ideal' & that length/style skirt gives the impression of longer legs too. Oh & peplums work well, for similar hip-volumising issues, as long as the waist seam matches my natural waist. Usually they hit too high, on my ribcage instead, which makes me look boxier. Empire waists are not the most flattering option.
As someone with a delicate, widely set bosom (traditional cleavage is pretty much a physical impossibility!), I've noticed body con knits with a round neckline (either crew or scoop) make me look bustier. And square necklines best play up my decolletage; I think because of the contrast between the straight lines of the clothing & the rounded lines of my chest.
My short neck looks longest if I'm either wearing my hair up or down at chin length or shorter.
I have to pay close attention to the armscye region; a lot of armholes hit significantly lower than my actual armpit, which makes for a sloppy looking garment.
My small curves look best in either very fitted looks to show them or deliberately waist surrendering/voluminous ones. The in-between ground of 'tailored,' like the traditional button down shirt, is very tricky, as it tends to just make me look boxy. Especially in wovens!
That's about all I can think of for now! In case it helps anyone else. This thread has been great fun to read!
