Got the idea from one of some works in pixiv where some original character is advertising some clothing brands.
Neru (the name of the character) is part of my original Story, We Are. Rilakuma is one of the new character of sanX and also my sister's favorite character.
the clothes pattern is just a resource/ texture that I found in pixiv.
