A theme that’s hard to dress up for. A theme makes decorating the venue easier, and perhaps can guide you when it comes to the food that you’ll be serving, but it might give the majority of your employees a hard time coming up with something to wear for the party. A good way to figure out if it’s a doable theme is if you yourself can come up with something to wear from what you already own, without having to rush out to the mall to buy something new, or take the time out to make something.
