The trick in Kim Mu-jin’s navy look in Love Is Coming is the gray collared knit: it softens the jacket without blurring the shoulder line. For a casual office or dinner, compare shoulder width and room through the chest first. The shopping links are similar styles, with the differences called out beside each item.
The Navy Double-Breasted Jacket and Heather Gray Knit
A standout piece in Kim Mu-jin's mid-season wardrobe is his deep navy double-breasted blazer. Double-breasted jackets naturally add width and visual presence across the chest, but this look avoids boardroom stiffness by pairing the tailored shell with a soft heather gray buttoned knit polo.
The contrast between the structured navy fabric and the melange heather gray base layer balances formal authority with comfortable movement. Notice how the three-button placket on the knit top remains partially unfastened to frame the neckline cleanly without competing with the jacket's peak lapels.

For readers looking to capture this structured yet casual balance, finding an accessible double-breasted jacket with neat shoulders is the first step. You can check the KSWYCT navy double-breasted blazer — similar style on Amazon for current sizing, cut specs, and material details. Underneath, a soft long-sleeve knit like the COOFANDY grey long-sleeve knit polo — similar style offers a comparable collar fold and multi-button chest placket for easy layering.
Khaki-Beige Tailoring with Peaked Lapels and Dark Underlayers
In Episode 13, Kim Mu-jin switches palettes with a tailored khaki-beige blazer that features distinct peaked lapels. Earthy tones can sometimes appear washed out under bright studio lighting, but grounding the khaki jacket with an ink-black buttoned underlayer sharpens the overall silhouette.
The deep V-break created by the single-button fastening works well for anyone wanting to elongate their torso. By skipping a tie and leaving the black knit collar relaxed, the chest area remains light and contemporary.
When wearing this combination off-screen, slim dark trousers or charcoal chinos help anchor the upper-body contrast without introducing conflicting color blocks.
Off-Duty Contrast: Waffle Knits and Athletic Shells
The ivory open-knit polo and pale jacket create a softer, more relaxed mood than the navy combination. The visible knit pattern adds interest without needing a bright print.
The pale gray zip jacket over a dark top gives a sportier option for a weekend walk or a casual meetup. Its upright collar and dark zipper create contrast without adding a busy pattern.
Keeping the palette to navy, gray, ivory and black makes these pieces easier to combine. Choose the zip jacket for a relaxed outing or the textured knit under a blazer for dinner. Check the garment label for fiber content rather than inferring it from the screen.
Style Takeaways and Proportions for Daily Wear
Replicating Kim Mu-jin's wardrobe comes down to smart collar choices and proportion control:
- Swap Stiff Poplin for Knitwear: Instead of woven dress shirts, choose medium-weight knit polos or henleys. The ribbed collars settle naturally beneath blazer lapels without curling awkwardly.
- Respect Shoulder Proportions: A double-breasted blazer demands clean shoulder structure. If you have a broader frame, unbuttoning the front jacket button creates vertical visual space. If you have a narrower frame, buttoning the inner anchor keeps the front panels tidy.
- Stick to Dual Tones: Notice how each outfit pairs two primary shades: navy with heather gray, khaki with pure black, or ivory with off-white. Limiting the palette prevents tailoring from looking cluttered.
