How are pencil skirts supposed to fit? I don't mean hem length or waist height; I'm talking more about the rest. I have been wondering about this for awhile, would someone please enlighten me?

I see some women wearing them fairly tight, tight enough they may even leave horizontal wrinkles, and yet it looks really good on them. But on me if I wear a pencil skirt that tight I just fear I look like a sausage or a snake that swallowed a small animal (my belly, not my butt... and you know it's the wrong fit if my belly sticks out more than my butt!) But if I wear them too loose, they don't look like pencil skirts to me. It seems you should be able to see some shape, no?

I'm mostly wondering because I have on my fall list: pencil skirts. I do like the look but the fit is always tough. I could use some very specific and detailed guidance....

To make matters easier, feel free to analyze/critique the fit of this pencil skirt that I wore for the YLF challenge:

This skirt usually hangs much looser on me. Since gaining a few pounds, when I first put it on for the challenge I thought it was now too tight. And yet, I see other people wearing them this tight, so I don't really know. It is a tad too tight in the waist but it zips and I could probably wear it out to dinner and be comfortable. Since my waist is relatively thick, that part is a given - I'm talking more about how it fits in the hips. Is this right?
