Oh, I love those pleated skirts and believe it or not, don't own a single one. Mainly because I have found, like you, that not all pleated skirts are made equal -- the pleats have to be done just so or they are girth expanding.
Having said that, I absolutely LOVE that you are wearing your velvet one all the time.
And I worry a wee bit that faux leather won't cut it because it will be too hot and also lack the "swish" factor. But I must admit, the idea intrigues, from a texture-in-the-outfit standpoint. Hmmm.
I would LOVE a silver pleated skirt. But skirts are mainly summer wear for me, so I'm not sure I will spring for it.
Meanwhile...on the question of duplication, I have enjoyed everyone's thoughts. I do duplicate, yes...fairly often in fact, -- mainly of wardrobe essentials in my key neutrals. But also, ahem, statement booties.
