I will wear colors to play along. I have a red sweater and red purse for Christmas stuff. I have a ski sweater...blue background with bright yellow and white patterns that work for Chanukah.
I would buy something holiday specific if I found the right item. My husband loves all of the "ugly" stuff, but I want something flashy yet tasteful. A woman at work last week was wearing this fully sequined top (may have been an oversized shift dress repurposed into a top). The background was iridescent white, I think it said HOLLY or JOLLY on the front, and the wording and little ornament style accents and stripes/bands at the sleeves/collar were varying shades of iridescent pink and green. There may have been more, but I didn't want to stare. Either way...it was flashy but tasteful.
