A New Season in RUNDHOLZ MAINLINE
The arrival of RUNDHOLZ MAINLINE SS26 marks a decisive shift in how we think about modern dressing. This is a collection rooted in confidence, movement and intent, where streetwear references are elevated through craftsmanship and sculptural precision. For Spring and Summer 2026, RUNDHOLZ MAINLINE takes familiar codes and pushes them forward, blending urban energy with the considered design language that defines the house. Available now for pre-order at House Of Valerie, SS26 is an invitation to dress with clarity, individuality and control.
This isn’t trend-led fashion, it’s ladies' designerwear that speaks to longevity and self-expression, offering pieces that work as bold statements or as quiet foundations depending on how they are styled. Throughout the collection, denim becomes a canvas, colour is deliberate, and silhouette remains central. SS26 feels fresh, but unmistakably RUNDHOLZ.
Monochrome
The monochrome story in RUNDHOLZ MAINLINE SS26 introduces graffiti-inspired artwork in a refined, wearable way. Rather than overwhelming the silhouette, the graphic elements are used to enhance shape and movement, grounding statement design in everyday functionality.

The sleeveless RUNDHOLZ MAINLINE top crafted from lightweight Cupro is an effortless entry point into the collection. The silk-finish fabric brings fluidity, allowing the cowl neckline to fall softly against the body. Spaghetti straps and a racer back keep the silhouette clean, while the layered front panel draws the eye downwards into a subtle knitted knot detail at the hem. This piece works beautifully styled with wide-leg denim trousers, allowing contrast between softness and structure, or layered under a jacket where the drape adds depth without bulk.

Denim takes on a more expressive role in the monochrome section through the hand-painted RUNDHOLZ MAINLINE trouser. Designed with an exaggerated drop-crotch and wide leg, the silhouette feels intentionally relaxed while maintaining architectural balance. Oversized back pockets and utilitarian strap detailing reinforce the streetwear influence, while the hand-finished graffiti artwork ensures no two pieces feel identical. These trousers work best when styled simply, paired with a fitted top or minimal knit to let the artwork and shape speak for themselves.

To complete the look, we adore the cropped stretch-denim jacket. Fitted through the body, this jacket introduces adjustable vertical gathering that allows the wearer to sculpt the silhouette. The concealed button fastening keeps the look clean, while the reworked jean detailing at the hem adds a subtle point of interest. Worn over monochrome separates or layered with graphic denim, it offers a sharp counterpoint to the relaxed proportions found elsewhere in the collection.
Electric & Ice
Blue tones dominate the Electric and Ice palette, offering a cooler counterbalance to the collection’s graphic energy. These pieces feel lighter, more fluid, yet remain grounded in the bold identity of RUNDHOLZ MAINLINE.

The longline Cupro tunic extends the language of the earlier vest top, elongating the silhouette while retaining the same soft drape and knitted knot detail at the hem. Its sleeveless design and racer back make it ideal for warmer months, while the length allows for versatile styling. Worn over painted denim trousers, it creates an intentional layered look, or styled alone with slim trousers, it becomes a fluid statement piece that moves effortlessly with the body.

Denim returns in a more sculptural form with the balloon-shaped RUNDHOLZ MAINLINE trouser. The rounded leg and oversized pockets are softened by subtle seaming and utilitarian straps, creating volume without heaviness. This piece feels particularly strong when styled with a fitted top or cropped jacket, allowing the shape to remain the focal point. The hand-painted detailing adds texture and individuality, reinforcing the idea of denim as wearable art within SS26.

The longline Cupro jacket brings a softer energy to outer layering. Its open-front silhouette and oversized patch pockets keep the look relaxed, while the knotted detail at the back hem introduces gentle structure. This jacket works beautifully as a finishing layer over tonal outfits, adding movement without disrupting balance. It is a piece that transitions seamlessly from statement styling to everyday wear.
Denim Wash
Denim sits at the core of RUNDHOLZ MAINLINE SS26, explored through a range of washes that feel lived-in, expressive and modern. From Indigo Faded to Chalky Paper, each finish brings a different mood to the collection while maintaining a consistent design language.

The tailcoat-inspired denim jacket introduces drama through proportion. Fitted through the body with a flared hem, it features exaggerated front pockets with attached utilitarian straps and a vent at the back. Adjustable inner drawstrings allow the wearer to shape the jacket to their preference, making it both sculptural and functional. This piece works exceptionally well layered over simple dresses or paired with wide-leg trousers for a directional silhouette.

The classic drop-crotch denim trouser returns in Indigo Stonewash, reinforcing the versatility of this shape. Oversized back pockets and relaxed proportions give the piece an effortless feel, while the fixed waistband and traditional denim detailing keep it grounded. Styled with minimal tops or layered with Cupro pieces, it becomes a foundation piece that anchors the more expressive elements of SS26.

A cropped, fitted denim jacket in a chalked stonewashed finish offers a sharper take on denim layering. The irregular distressed markings give each piece a hand-treated appearance, adding depth and individuality. Adjustable gathering allows for sculpting, while the cropped length makes it ideal for balancing volume elsewhere in an outfit. This jacket works beautifully over longline tops or paired with high-waisted trousers for a considered, modern look.
Ketchup
Bold and unapologetic, Ketchup red introduces a vibrant energy to the SS26 palette. Used thoughtfully, it becomes a focal point rather than an overwhelming statement.

The Cupro jacket in Ketchup is fluid, lightweight and expressive. Its open-front silhouette, oversized pocket and multiple knot details create interest without excess. The tie at the back of the neckline adds an unexpected detail, allowing the piece to feel finished from every angle. This jacket works beautifully styled with Paper or Marshmallow tones, offering contrast while maintaining balance.

The RUNDHOLZ MAINLINE scarf continues the colour story in a softer way. Crafted from semi-sheer cotton poplin, it features circular stitched gathering that creates movement and texture. Draped loosely or wrapped with intention, it offers a way to introduce colour into everyday looks. Styled alongside graffiti denim or layered over neutral separates, it provides versatility and ease.

The graffiti-painted cropped denim jacket is the perfect statement piece in Ketchup. Hand-finished artwork, adjustable gathering and a fitted silhouette make this piece both expressive and wearable. It pairs seamlessly with coordinating trousers or acts as a standalone statement over simple foundations.
