Elena Romanova is, uh, a model on Instagram? We don't really know how best to describe her, since we only just discovered her this morning. On Instagram. Doing stuff that models do. You know, like wearing a thong while climbing the side of a train. Or wearing a thong out on the fire escape while taking her top off. Or wearing a thong while picking fruit. It's possible she specializes in activity-based thong modeling (ABTM). That's a thing, right? Anyway, Elena's real good at it.
