In Certificate of Family Relations Episode 67, Lim Ji-hoo's styling centers on effortless smart-casual balance. Before the major family clash unfolds, he pairs a heather grey fine-gauge knit polo under a dark tailored jacket, giving off a grounded, polished feel that transitions straight into home wear when he sheds the outer layer. If you've been eyeing that clean knitwear look, here's the full breakdown of how the piece functions on screen and how to replicate the aesthetic with a practical similar pick.
Lim Ji-hoo's Episode 67 Knitwear Breakdown
In the opening sequence of Episode 67, Ji-hoo steps out wearing a tailored dark jacket layered over a heather grey knit polo shirt with a classic fold-down collar and button placket. The pairing sets a mature tone without feeling overly rigid like a conventional dress shirt and tie.

When he heads back to his family home to confront his parents over the forged marriage registration papers, he strips off the blazer, leaving the grey polo as the primary silhouette for the rest of the heated confrontation. The garment features a heathered grey hue with subtle ribbing along the collar and cuffs, balancing relaxed loungewear comfort with sharp lines around the neck.
Recreating the Look: The Grey Knit Polo
To capture this exact smart-casual vibe, look for a fine-gauge knit polo rather than standard pique cotton golf shirts. Pique weaves can look sporty, while smooth knit sweaters hold their drape cleanly under structured outerwear.

You can check out the COOFANDY grey long-sleeve knit polo — similar style to replicate the same neckline and heathered grey colorway. It mirrors Ji-hoo's piece with its ribbed polo collar, three-button placket, and knit texture. While Ji-hoo's screen-worn shirt leans slightly more fitted through the torso, this alternative offers a relaxed regular cut that works well tucked into tailored slacks or worn loose over dark denim. Be sure to check the merchant's listing directly for current sizing, color variations, and shipping terms.
Styling Tips: Layering and Proportions
If you want to style a knit polo like Ji-hoo did in this episode, keep the proportions balanced:

- Under Tailoring: Layering a collared sweater underneath an unstructured blazer keeps the lapels sitting neatly without collar bunching. We saw a similar layering approach in the Love Is Coming Episode 19 Outfits: Piped Blazers, Knit Polos, and Summer Shirting breakdown, where clean collar bands helped frame the neckline.
- Solo Silhouette: When wearing the polo on its own, pairing it with medium-rise dark trousers or neutral chinos keeps the top from looking like casual gym gear. A tucked hem emphasizes a clean waistline, while leaving it untucked keeps the mood relaxed.
