IU PSL Score: The Korean Domestic Standard
IU (Lee Ji-eun) occupies a unique position in PSL community analysis — she is the primary reference for what the Korean domestic beauty standard means in structural terms. Unlike K-pop idols primarily exported for global visibility, IU's attractiveness standard is calibrated to Korean aesthetic preferences, which creates interesting comparison opportunities to globally calibrated PSL.
Facial Thirds as the Primary Halo
IU's facial thirds are her most consistently cited structural halo — near-ideal proportional balance that photographs well across diverse contexts. Combined with near-perfect bilateral symmetry and positive canthal tilt, her overall harmony creates the structural case for Stacy tier despite no single metric being at the absolute maximum (unlike Lisa or Hadid).
Korean vs. Global PSL Calibration
The community discussion around IU includes a calibration debate: does the Korean aesthetic standard (which emphasizes facial proportions and skin quality more than jaw definition) inflate or accurately assess her relative to globally calibrated PSL? The consensus: her global structural metrics genuinely support 6.5–7.2 Stacy regardless of calibration framework, with the Korean standard slightly inflating the upper bound estimate.
