Sequin pants, or any shiny pants for that matter, never look good on unless you are a size double zero, like the above mannequin. These are Les Chiffoniers Sequin leggings. I think this outfit is very hot, but I couldn't pull it off. I once had a gorgeous pair of skin tight Betsy Johnson metallic snakeskin pants, and I was a size zero at the time and they made me look fat. No, I'm not anorexic, nor did I have an unrealistic body perception. They made me look fat. For some reason shiny pants seem to add size to whomever is wearing them.
Posh Spice would look good in these pants. Do you like them? Available at Net a Porter, $815.
