As September arrives with cooler weather, a distinct fashion trend is emerging: the "back to school" look, re-imagined for adults. This style draws inspiration from traditional school uniform elements, incorporating pieces like loafers, cardigans, checks, blazers, and pleats into contemporary wardrobes.

Designers are leaning into this preppy aesthetic for the Autumn 2026 collections, offering a sophisticated take on familiar items. The trend suggests a way for adults to feel a renewed sense of optimism for the changing season, mirroring the back-to-school transition.

The key elements of this trend include:

Argyle Cardigans

Cardigans are making a comeback, particularly those featuring an Argyle pattern. These can be worn buttoned up with trousers or layered over shirts, offering a nod to school uniform nostalgia without appearing juvenile. For example, a collared sweater with an additional cardigan draped over the shoulders or waist is a look seen on recent runways.

Below-the-Knee Pleated Skirts

When incorporating pleated skirts, the key to maintaining a grown-up look is the length. Skirts that fall below the knee, but are not maxi length, are considered chic. These can be styled with fine-knit jumpers and loafers for milder weather, transitioning to boots and chunky sweaters as temperatures drop.

Oversized Blazers

Inspiration for blazers comes from the practical approach of purchasing school uniforms that allow for growth. An oversized or roomy blazer provides enough volume for layering underneath, offering a relaxed yet polished silhouette. This contrasts with fitted business styles.

Classic Loafers

Flat footwear is prominent, with loafers in leather or suede being a top choice for autumn. The emphasis is on simple, classic designs in black or brown, avoiding chunky soles or excessive detailing. These styles, reminiscent of those worn in school days, are now fully accepted in adult fashion.

Checks Everywhere

Checks are a dominant print this autumn, appearing on more than just coats and blazers. This season, the pattern is extending to skirts, trousers, shirts, and even accessories like bags and shoes. This versatile print offers a timeless appeal for various garments.
