>>2204869Narrow shoulders, or shoulders that are at least smaller than the hips are needed in order to be pearshaped. The breasts don't need to be small, they just have to be smaller than the hips.
>>2205607Yeah, there's no singular tag for this. Sometimes you can use the small breast tag by itself and find pics of pearshaped girls who weren't also tagged as wide hips/thick thighs/ huge ass.
