It's no secret that style-watchers are focusing in on collars. It's a trend that's relatively easy to pull off. There are tons of options out there: the removable collar, the collar necklace and (please, don't laugh) the dickey. For those of you who do not know, the dickey is basically a collar that is attached to a "bib" and gives the illusion you are wearing a shirt. Dickies can change the look of a sweater or shell without any bulk or pesky bunching and twisting. They are especially handy to a Texan (like myself) who appreciates the layered look, but rarely sees the opportunity, what with the heat soaring well through fall!
