A previous year purchase that turned out to be a year on year smart casual staple was a long cardigan twin set. I bought this set 3 years ago and it comes out once or twice each winter or early spring. This set is not constrained by fashion. The hem is straight so not linked to any era of waterfall or hankerchief styles. A twinset for winter will always look chic to my mind. In fact I so liked this set that I bought it in turquoise too. In the spring I intend to wear the cardigan over white vests.
Do you have any staples that you wear and wear?
