I haven't seen a perfect twin yet, though I identify with Sveta's overall proportions, despite our difference in height. Overall, I seem to be the definition of "medium" when it comes to store clothing. Fairly proportional and on the tall-ish side.
I am posting numbers because I have found others' numbers helpful as opposed to daunting - my intent is solely to provide information, no judgement.
My current numbers in the bust are a bit different from my "typical" numbers since I am still nursing my baby. However overall my weight and size are luckily very stable.
5'-7", 145-150 lb
Usually Pear tending toward X-shaped Hourglass, currently fully Hourglass
slender wrists, ankles, hands, feet
bony, sharp-ish shoulders
long neck
longish arms
long-torso, mostly from being long-waisted but also long-in-the-rise
longish calves, shortish thighs
muscular lower body in general compared to upper body
size 10 bottoms (sometimes 8)
30" waist
32" low waist
40" low hips
Usually 34B bust (36"), size 6 tops
Currently 34DD (39"), size 8 tops (sometimes 10)
size 7.5 to 8 (38) shoes
So far Debby and VC sound the closest?
Some silhouettes that work well for me are:
high necklines, especially bateau but also turtlenecks
body-con tops
cinching belts
A-line and pencil skirts with hem lengths no shorter than top of knee
high-waist jeans and trousers (and skirts)
jackets with structured shoulders and nipped / tailored waists
Sheath dresses
Silhouettes that don't particularly suit me:
V-necklines
short skirts or dresses (more than 1-1.5 inches above the top of kneecap)
"modern fit" (straight-leg) trousers
boots over jeans (my calves are too muscular; boots just barely fit over thin socks)
Dresses with details at the waist (which are usually positioned too high relative to my waist)
Calling all twins...?
