Surely trhe answer must be when it gets short enough that a guy would not have to use his imagination...
Place your arms by your sides and where the middle finger's tips are is how short the skirt should be.
Just wear tights under the mini skirt if you're worried about looking trashy
It really depends on the style of skirt and sweater, but given the right accessories I don't think there is anything inherently nerdy about that combo
A short tulle ballet skirt is called a tutu.
short / mini skirt
a pair of dazie dukes are about the size of a skirt
Mullet Skirt :)
A short skirt is a skirt that comes at the knees or even shorter above the knee
I think it does but the leggings have to be long and the skirt has to be short
I certainly wouldn't wear it past 25 and even then that's pushing it, it's often best to leave miniskirts up to the teenagers and to go for a classier longer skirt. ------------- There's no age limit. Older women are beautiful and sexy when using a miniskirt.
The answer to your question depends on the the reason you are wearing the skirt or shorts. If it is something dressy I would say a skirt, but sporty shorts. You could always do a skort. That is a short that looks a skirt, but wears like a short. I would also like to add a suggestion here for you. If you are wearing one of the popular really short skirts or dresses before you sit down hold down the hem of the skirt or dress before you sit. It will help you sit better and not show all your bits/parts.
If your skirt is really to short, people will tell you. Honestly, it will make you look easy and desperate.
