Lin Zhixia’s Structured Black Blazer on Campus
Lin Zhixia makes a commanding appearance in the campus dining hall wearing a tailored black blazer over a light inner tee and dark bottoms. The crisp lapels and padded shoulder lines immediately set her apart from the casual student crowd, signaling her focus and academic standing.

An oversized blazer works exceptionally well for creating a balanced inverted triangle silhouette, especially when paired with fitted bottoms or shorts that keep the lower half streamlined. For petite frames, choosing a cut that finishes mid-hip rather than mid-thigh helps preserve leg length.

To channel this minimalist smart-casual presence, consider the Genhoo women stretch office blazer, black — similar style (paid link). The piece features a stretch fabric construction and clean front closure suitable for office or casual rotation. While Lin Zhixia's onscreen jacket features customized costume tailoring, this similar option provides a practical way to achieve a structured profile.

Zhang Yubai’s Rugged Utility and Shirt Layering
In sharp contrast to Lin Zhixia's sharp tailoring, Zhang Yubai’s look reflects the chaotic demands of his repair workshop. Throughout the episode, he wears dark utility outerwear and relaxed button-up shirts worn open over solid crewneck tees.

Leaving a button-down shirt unfastened establishes strong vertical lines down the chest, which flatters broader shoulder builds without adding extra visual weight. Rolling the cuffs to mid-forearm emphasizes a practical, ready-to-work aesthetic that suits weekend errands or relaxed creative spaces.
For an everyday base that replicates this layered approach, take a look at the Amazon Essentials men cotton Oxford shirt, blue — similar style (paid link). Built with 100% cotton in a regular-fit long-sleeve silhouette, it serves as a reliable outer layer over a neutral undershirt.

Autumn Knitwear and Printed Scarf Accents
During the outdoor park scene under the autumn trees, Lin Zhixia shifts to a warmer, softer palette with an ivory long-sleeve top accented by a patterned scarf draped loosely around her neckline.

A patterned scarf instantly elevates a basic light knitwear piece, creating a natural focal point near the face while providing practical warmth in breezy transitional weather. Paired with a soft side braid, the styling softens her character's usual sharp collegiate sharpness.

Pair the jacket with clean everyday basics such as a solid crewneck t-shirt, relaxed denim, or tailored shorts. Pushing up the sleeves slightly softens the rigid shoulder construction for an effortless daytime look.
What shirt fabric works best for recreating relaxed casual layering?
Medium-weight breathable fabrics such as cotton Oxford cloth or lightweight cotton twill hold their drape cleanly when worn open over an inner tee, avoiding unnecessary stiffness.
