I use different hangers for different items. My jackets and coats are on wooden hangers because I think they support the shoulder line better. My shirts, dresses, and sweaters (yes, I hang sweaters by folding them on the hanger) are on the skinny velvet hangers, my pants hang from the hems on clamped pant hangers, and my skirts are on a tiered skirt hanger. I use plastic hangers to dry shirts and dresses because I'm leery of transferring dye from those velvet hangers.
My mix-and-match approach doesn't make my closet look like the ones in the design magazines, but it is functional and, more importantly, keeps my clothes in good shape.
