I'm going to ride the fence on this one and say it's a mixture of both. She probably can't find a bra that actually fits her properly, I mean look at her, so she's probably got a mixture of side fat and boob fat going on there in a bad case of "migrating tissue" that pushes her breast "tissue" under her armpits. Any way you look at it, it's gross. 0/10, would not recommend.
