Side Split Jumpers: The Ultimate Guide to Styling & Shopping

Side split jumpers are the perfect solution for adding movement and modern edge to your knitwear collection, offering a flattering silhouette that works beautifully for both casual and elevated looks. I've been styling clients with these versatile pieces for years, and they're absolutely brilliant for creating that effortless, contemporary aesthetic whilst still being incredibly comfortable. The strategic side openings not only add visual interest but also create a more fluid drape that's incredibly flattering on all body types.

Why Side Split Jumpers Work So Well

As a stylist, I'm constantly amazed by how side split jumpers solve so many common styling dilemmas. The split detail prevents that boxy, overwhelming look that traditional jumpers can sometimes create, instead offering a more tailored, sophisticated silhouette. The openings allow for layering opportunities – think slip dresses underneath or high-waisted trousers peeking through – whilst the relaxed fit remains comfortable for all-day wear.

The beauty of side splits lies in their versatility. They work with virtually every body shape, creating vertical lines that elongate whilst the relaxed fit doesn't cling. For petite frames, they add length without bulk, whilst for curvier figures, they skim beautifully without being restrictive.

How to Style Side Split Jumpers

The Layered Look

One of my favourite styling tricks is wearing a side split jumper over a midi slip dress or camisole. The contrast between textures creates depth, whilst the split allows glimpses of the underlayer. Choose complementary colours – a cream knit over a burgundy slip dress is particularly striking for autumn.

High-Low Proportions

Pair your side split jumper with high-waisted bottoms to create that perfect high-low proportion. Wide-leg trousers work beautifully, as do high-waisted jeans. The key is ensuring the waistline of your bottom piece hits at or just below the natural waist to create the most flattering silhouette.

Accessories Matter

The relaxed nature of side split jumpers means you can afford to be bold with accessories. Statement earrings, layered necklaces, or a structured belt worn over the jumper can completely transform the look from casual to evening-appropriate.

Fabric and Fit Guide

When shopping for side split jumpers, pay attention to fabric composition. Wool blends offer structure and warmth, whilst cotton mixes provide breathability and are ideal for layering. Cashmere, whilst luxurious, requires more care but offers unparalleled softness and warmth.

Fit-wise, look for pieces that skim rather than cling. The shoulders should sit properly, and the side splits should fall naturally – they shouldn't gape or pull. The length should hit at your most flattering point, typically mid-hip to upper thigh.

Seasonal Styling

Side split jumpers work beautifully across seasons. In autumn and winter, layer them over turtlenecks or under blazers. Spring calls for lighter weights worn with cropped trousers or midi skirts. Even summer evenings can benefit from a fine-gauge side split jumper worn over slip dresses or with linen trousers.
