IU's Chaebol Heiress Style
in Perfect Crown

Seong Hee-joo has everything — except royal status. IU's wardrobe in MBC's Perfect Crown is the blueprint for contemporary Korean power dressing: structured blazers, impeccable tailoring, and the quiet confidence of someone who runs a billion-dollar beauty company.

👑 Now Airing: Perfect Crown premiered on MBC and Disney+ on April 10, 2026. This guide will be updated weekly as new looks air. Bookmark this page.

In Perfect Crown, IU plays Seong Hee-joo — second daughter of the Castle Group chaebol family, and CEO of Castle Beauty. The setting is a fictional 21st-century Korea operating as a constitutional monarchy. Hee-joo is ambitious, sharp-tongued, and dressed at all times like she owns every room she walks into.

The character description IU herself gave: "탐욕, 기질, 귀여움." Ambition. Temperament. Cuteness. Her wardrobe tracks all three: structured power blazers for the boardroom scenes, softer tailored sets when her defenses come down, and formal wear when the royal court demands it.

Where IU's previous drama Hotel del Luna gave us vintage luxury and When Life Gives You Tangerines gave us Grandmacore warmth, Perfect Crown delivers Chaebol Chic — polished, deliberate, and unapologetically expensive-looking. Here is how to wear it. For more K-drama fashion inspiration, explore our K-Drama Style page.

Chaebol Chic

Seong Hee-joo (성희주)

Perfect Crown (2026, MBC / Disney+) — Played by IU (Lee Ji-eun)

Power Dressing CEO Tailoring Old Money Korea Royal Adjacent

Hee-joo is the daughter of a chaebol family who has built her own empire running Castle Beauty. She is described as "탐욕스러우고 기질 있고 귀엽다" — greedy, spirited, and cute. Her fashion reflects exactly this: extremely polished on the surface (structured blazers, tailored trousers, subtle gold accessories), but with flashes of personality that keep her from looking cold. Think the Korean equivalent of a Wall Street power suit — but softer in silhouette and always with perfect accessories.

Seong Hee-joo CEO Entrance — cream blazer power look

Look 01

The CEO Entrance

Hee-joo's boardroom look: a perfectly structured blazer in cream, ivory, or pale grey — always single-button, always fitted at the shoulder. Worn with high-waist wide-leg trousers and a silk or satin shell underneath. Gold accessories kept minimal but present: small hoops or a thin chain necklace.

Look 02

Soft Power

When Hee-joo's "귀여움" (cuteness) shows through — a monochrome matching set in warm camel, taupe, or cognac. Fitted knit top with tailored midi skirt or trousers. Still polished, but with a warmth the CEO look doesn't have. A small structured crossbody bag and pointed flats complete it.

The Chaebol Chic Formula

Hee-joo's style follows one rule: investment pieces, minimal quantity. One perfect blazer outworks ten fast-fashion alternatives. The color palette is always neutral — cream, ivory, camel, taupe, occasionally deep navy. What elevates the look from "nice outfit" to "she runs a company" is fit: everything is precisely tailored. If you're shopping a blazer or trousers for this aesthetic, go one size smaller than you think and get it hemmed.
