I am in need of a suit for fall. Ideally, I would like a nice suit that I can wear in three seasons, in dark gray or charcoal.

I found this suit at New York and Company:

Pants:

I didn't see it in the store, yet so I don't know about the quality but it seems nice. If you have seen it in person, I would appreciate your feedback.

Also, what is interesting is that it also has a matching skirt and a vest:

Skirt:

Do you think it would be a good idea to buy all 4 pieces? Would it be really versatile? Or should I save my money and buy another pants or skirt suit?
Thanks for your input.
