Grandpa Core at Work: How To Wear the Vintage Office Trend of 2025

Grandpa core didn’t just appear out of nowhere, it’s a style decades in the making. While the look is trending in 2025, its roots go back to a time when getting dressed meant putting thought into every layer. Think wool cardigans, pressed slacks, polished leather shoes, and a good tie.

In recent years, younger generations began embracing that slower, more intentional approach to dressing. Whether pulled from vintage racks or actual family closets, pieces like shawl collar sweaters, argyle sweater vests, and houndstooth sport coats started to reappear as everyday wear. Social media helped fuel the revival, with creators showcasing outfits inspired by their own grandfathers’ wardrobes.

Bringing back the classics: Grandpa core style leans into timeless staples like vests and neckties.

Grandpa core may draw inspiration from the past, but it’s surprisingly office-ready. This trend blends soft layers, relaxed tailoring, and vintage accessories to create a look that’s equal parts professional and personal. Whether you're updating your business casual routine or just want to stand out with subtle style, grandpa core makes a confident (and comfortable) statement at work.

Grandpa core is all about layers that feel lived in:

• A button-down oxford shirt with soft structure
• A sweater vest, cardigan or knit pullover
• A lightweight blazer or wool jacket when needed

These pieces add depth without looking fussy.

Ditch the ultra-skinny fit. Instead, opt for:

• Pleated trousers
• Relaxed-fit chinos
• Wool dress pants with a bit of drape

Belt it like your grandpa would—or go beltless for a cleaner finish.

The right necktie pulls the whole look together. Choose styles that feel nostalgic but office-appropriate:

• Wool ties for texture and warmth
• Muted stripes for subtle throwback flair
• Plaid ties that channel timeless, scholarly charm
• Wider widths (3.25"–3.5") for that retro silhouette

While women can certainly wearing neckties, consider swapping the tie for a bow tie or neck scarf. Mix traditionally masculine and feminine pieces. It’s all about personal comfort and charm.
