I love the look of a sheath dress, so timeless and elegant. During the cold weather months, you can change the look by pairing a turtleneck sweater with a fitted sheath dress. This is a great way to wear your classic dress and not have your arms exposed when it's chilly. It also gives the the dress a more casual look.
"Create a clean base with a thin, stretchy turtleneck; top it with a short-sleeved, tailored shift dress that has flattering details like a low neck and a nipped waist."
