Though once associated with the highest of upper class events (as it still is today in Britain) the white and off-white tie has become the rarest of sartorial choices across the pond where we live. That said, an off-white skinny tie seems to be a little more common than a standard sized ivory or cream tie.
For those who really want to stand out, wearing an ivory or bamboo skinny neck tie with a black suit can really create compelling and classy effect if done well. If you are organizing a wedding an off-white skinny tie might also make sense, allowing you to match the grooms or groomsmen. And an off-white skinny necktie can also be a cool choice for the prom. For less casual events, you might also consider a knit skinny tie in cream like that offered by the king of knit ties himself, Jacob Alexander.
