What age to stop wearing mini skirts?

As I go through boxes I am sorting through clothes that have been packed up for six months.  Stuff I forgot I had.  Stuff I have not worn for two years.  Lots going to Goodwill.  My question of the moment is:

Can a 31 year old working mom of two wear a jean mini skirt?
Can a 31 year old mom wear a mini skirt?
Can a 31 year old woman with no kids wear a mini skirt?

I have it.  It is on the floor of the closet.  Does not look half bad if I can say so myself.  Looks better than some of the teenagers I see in mini skirts.  Still fits, after two kids, impressive.  Don't think I will ever wear it again.

According to TLC, the source for all things, no mini skirts for someone in their 30s:  http://tlc.howstuffworks.com/style/10-things-not-to-steal-from-your-tweens-closet1.htm

"Even if you happen to look great in a tennis skirt on the courts, don't borrow a mini from your daughter's closet. Still tempted? It may help to gain some perspective: Before a fashion staple like the mini-skirt goes mainstream, it begins as a design for women in their 20s and is then adapted for younger ages -- like your tween who now pairs her mini with colorful leggings.

Why does this matter? Skirts more than four inches (10 centimeters) above the knee were never intended for those of us in our 30s or beyond. But that doesn't mean we can't adapt the trend. Pair a knee-length skirt -- it's the most universally flattering design -- with knee-high riding boots. It allows you to show off your curves without pretending you were born during the Clinton era. Trendy? Yes. Desperate? No."
