I'll take a Champion in a Onesie any day.

We have some GREAT skins where Champions are in onesies. But putting Star Guardian Champions in their own Star Guardian onesies isn't nearly as rewarding as it could have been.

Alternative Options:

1. Put Champions in onesies of other Characters. I've been wanting to see Vi in a Blitz hoodie with yellow Blitzcrank Gauntlets for years.
2. Put the Star Guardian onesies to other Characters. People have been begging for Star Guardian Gragas/Urgot/Taric FOR YEARS. This could have been a nice nod to that.
3. Put non-LoL onesies on Characters like you've done in the past (Meowkai, Dino Gnar, Reverse Annie, Moow Cow Alistar, etc).

I'll chalk this Pajama skin line up to good idea, poor execution.

As a side note, the spelling of Pajama is Pyjama in Australia/UK. (Also, Irelia's passive should be spelled Fervour instead of Fervor in Australia/UK).
