Should I buy Emma skin?

I used to be Emma main, and Mike is my fav character, I'm not sure if I should get Emma's skin, it's really cute, but soon Mike will also have the S skin, I have I can buy more echoes, it's just a bit much for me. 💦

I also have a 30% off card, but it runs out before February 8th so I can't use it for Mike’s skin
