Seoul Fashion Week 2025: Mastering the Retro Street Look with an oversized blazer

The oversized blazer has transitioned from a vintage find to the ultimate power player in Seoul's fashion scene. At Seoul Fashion Week 2025, this silhouette dominated both the runways and the streets of Dongdaemun Design Plaza (DDP), proving its versatility across various subcultures.

Seoul Fashion Week 2025: The K-Fashion Keywords

This season, the intersection of retro aesthetics and high-street functionality took center stage.

Retro & Street Mix: A blend of nostalgic 90s tailoring with modern techwear elements.
Practical High Fashion: Styles worn by dance crews and influencers that bridge the gap between performance and luxury.
The Hero Silhouette: The oversized jacket has emerged as the core piece for creating the "Seoul look."

The Anatomy of a Retro Silhouette

What makes a blazer "Seoul-style"? It’s all in the proportions.

80s-90s Tailoring Reimagined

Modern K-fashion takes the exaggerated shoulder pads of the 80s and the boxy fits of the 90s, refining them with cleaner lines. The goal is a structured look that doesn't feel heavy.

Genderless Appeal

The oversized blazer is the ultimate gender-neutral item. In Seoul, you’ll see the same cut worn by male models with wide trousers and female influencers with mini skirts, breaking traditional fashion boundaries.

From Dance Crews to Runways

The influence of K-dance culture cannot be ignored when discussing street style.

Dance Crew Style: Pairing a massive blazer with jogger pants or cargo trousers and chunky sneakers for maximum movement and impact.
Model Off-Duty: Top models often contrast the bulk of the blazer with sleek slip dresses or long boots for a high-contrast, chic look.

Daily Styling Formulas

You don't need a runway to pull this off. Here is how to incorporate it into your routine:

The Office Edit: oversized blazer + tailored slacks + crisp white shirt.
Weekend Casual: oversized blazer + hoodie + straight-leg denim.
Night Out: oversized blazer + mini skirt + knee-high boots.

Color & Fabric Trends

While black remains king, Seoul is seeing a shift toward earthier, vintage tones.

Colors: Deep browns, charcoal grey, and muted khaki are leading the retro wave.
Materials: Wool blends for structure, tweed for texture, and vegan leather for a modern edge.

Shopping Checklist: Getting the Fit Right

When buying online, "oversized" doesn't just mean "too big."

Shoulder Width: Ensure the pads sit slightly beyond your natural shoulder but don't sag.
Length: A true oversized fit should hit mid-thigh or just below the hip.
Sleeve Volume: Look for sleeves that allow for layering a thick knit underneath.

Essential Pairings to Complete the Look

To truly capture the Seoul street vibe, focus on your accessories:

Graphic Tees: Add a pop of personality under the lapels.
Footwear: Switch between loafers for a preppy look and techy sneakers for a street vibe.
Headwear: A simple baseball cap or a beanie can instantly ground a formal blazer.

Global Style Tips: Adapting the Look

Warm Climates: Opt for linen-blend blazers that offer the same silhouette without the heat.
Concert Ready: Choose a blazer with unique hardware or reflective details for a K-pop festival look.

Common Styling Mistakes to Avoid

Ignoring Proportions: If the top is huge, ensure the bottom is either very slim or intentionally wide—avoid "awkward middle" fits.
Too Much Fabric: If you are petite, use a belt to cinch the waist of an oversized blazer to prevent being "swallowed" by the garment.

FAQ

Q: How do I choose the right size for an oversized look? A: Usually, sticking to your true size in a designated "oversized" range is best. If it's a standard fit, go up 1-2 sizes.

Q: Can I wear an oversized blazer to a formal wedding? A: Yes, if paired with matching trousers and polished accessories, it creates a modern, sophisticated suit.

Q: What is the best inner layer for a boxy blazer? A: A fitted turtleneck or a simple crop top provides a great contrast to the outer volume.

Conclusion

The oversized blazer is more than a trend; it's a versatile tool for self-expression in the K-fashion world. Whether you're aiming for a retro vibe or a modern street aesthetic, the key is confidence in the silhouette.
