Stuff like this makes me glad I am self-employed. Count me as another non-fan of "ugly sweater days." For one thing, I'm not spending good money on something I find ugly, sorry. Especially not one that I'm going to wear for 8 hours and then throw in a Goodwill bag. And then there's the professional appearance thing, as it applies in this case. But I also wonder why the invitation to partake in festive dressing needs to be ugly-fied. Why can't it be "sparkly day" or "hat day" or something?
I realize some people will think I'm just being Grinchy, but I'm not much of a rah-rah-Christmas person anyway. I enjoy the season, for the most part, but these sorts of forced themes are just one more added stress to an already-full holiday season for most people.
