I’ve not found any that I like either, we have two sets each year - one for a Christmas film night the night our decorations go up and then another set for Christmas Eve.
The Christmas film night ones can be tacky so ds1 has some of the ‘merry Christmas ya filthy animal’ ones and ds2 and ds3 have a reindeer racing car set from H&M. For Christmas Eve I’ve just brought some from a website which are tartan bottoms and a reindeer on the top but they aren’t as nice as they sound, I’m really disappointed this year.
I found some on eBay that are two different pairs one saying naughty and one saying nice, I was going to get those for all 3 boys and make out that our elf had seen their names on the naughty list so they need to start behaving to get on the nice list and then give them the nice pair on Christmas Eve but I thought ds2 might not find it funny!!!
