A term popular in Japan. It describes a cute girl who is not necessarily plus size, but doesn't fit the skinny stereotype of Japan (and pretty much the rest of the world).
La Farfa magazine is a pioneer of featuring Marshmallow Girls. Their models usually weigh between 60 - 120kg (about 130-230 lbs).
Here is a quote from their editor-in-chief:
âWe donât promote losing weight or gaining weight, because there are women that look gorgeous regardless of what they weigh...Our view is that people should not be defined by the size of the clothes they wear."
Marshmallow Girl Goto Seina is so cute!!
