IU (Lee Ji-eun) vs Sofía Vergara

IU's facial proportions are consistently cited as near-ideal — upper, midface, and lower thirds in the golden proportion. This is her most consistently cited structural halo.

While proportionally excellent, her overall feature scale is small, which in some Western PSL frameworks rates slightly lower than larger-featured phenotypes at the same proportional quality.

Maximal femininity markers: full lips, round eyes, high cheekbones, feminine facial thirds. The peak-femininity Stacy profile.

Rounder eyes reduce the 'sharp' quality that extreme canthal tilt creates in narrower eye shapes.
