This year's parties are going to be completely different, so instead of your regular formal clothes, you might want to choose more casual party costumes. Whereas in the past, you may have looked forward to significant events or gatherings over the holiday season, such parties are unlikely to be achievable in 2021.
Other restrictions apply depending on where you reside, such as how many people can gather at one time and if you can mix with persons from different homes.
If you manage to throw or attend a party this season, it will undoubtedly be low-key. As a result, you'll most likely be considered more casual clothing than you would normally wear to a joyful occasion.
