unfrumped, I'm 5'4" or so. I got the regular sized, which is what my fit calculator recommended. Actually, I went exactly with my fit calculator and as you see, the fit was perfect.
I think Sveta still considers herself a pear....you can see her try on of the skirt in her thread.
It's funny...it does not feel like a "lot of skirt" for me....though I understand what you are talking about. I think in my case, my rather wide shoulders balance it out. And I plan to wear for dressier occasions, not work, so the feminine vibe of it will work for that. Date night, readings, parties...that kind of thing.
I do think Sveta also has broad shoulders, despite her saying she is a pear. I would call her more of a slim hourglass these days....
You are also on the slim side of the spectrum. I think in your case it would be a question of whether the waist fits in the right place, no? As in torso length.
