I subscribe to many litle fashion newsletters because my job does not really allow me to stay abreast of the latest trends, and I like to see what's happening on the fashion scene, even though, really, I am SO not a part of it.
Most of it I look through quickly, some of it I dismiss due to my own modesty preferences, but it was nice to know green nails were the newest "in thing." That way I was not QUITE as astonished when the cutie pie clerk at Target had pistachio colored fingers. (I actually have a nice minty shade on my toes and fingers currently.) I'm surprised by how much I like it now.
