Is the new year set even worth it to get?

I am asking because honestly I see no use to it. For the sleeves I have the new dress as a reward from the quest, maybe it can be useful for an off the shoulders outfit or mini skirt, but is there even a toggle for only skirt/only shirt? and is it even possible to layer it without too much clipping?

As for the jewerly... idk, it doesn't really tell me anything.

I might get the heels because I don't have many shoes combo, but since I would also love to get the new pose pack, I was thinking of skipping the dress set.
