Grey Pencil Skirt

I usually wear it with black or red shirt and I wear it at work. My friend loves black nylons, but I do not know when it is fashionable or appropriate.

Yes, you can wear black nylons with her.
I will say that nudity or pipe Solar is also very good!
I agree with Amanda and Brandi. bare-legged look is OUT!

You can wear the stockings. The pencil skirt covers you enough. If you do not feel comfortable, make the transition to opaque tights. Sounds like a very nice work clothes with me, though:]

While gray is dark gray and not a very light gray (Pearl), dark hosiery is fine.

Absolutely ... as long as you wear black heels, black nylons (pure or opaque) will be very cute.

nylons are ok .. work .. I mean like i wouldnt be somewhere other then work .. he will seek to tile .. as u is gray and black look so plainnn .. spicee it upp a bittt littile ... I think a red shirt is better than the black .. cute but add things to her like a pearl bracelets or pearl necklace .. Im sure you'll look afterwarddss hott.
hope this helps

toys go for it will look great

Yes, it is a very Forward Look!
=)

Of course, you can wear black tights with it. You'll look fabulous. And your friend has good taste. I'm with Amanda, bare legs look is OUT!

Of course, black nylons / hose would look great with it. You can also go with nude colors if you want.

Black is the best. But naked can also work. Brandi and thank you for phlvngal wear as a lady should!
