The Rise of Balloon Pants

After barrel jeans, fuller, rounder balloon pants have been appearing again and again, from the SS26–FW26 runways all the way to SS27 menswear. We look at the new flow emerging in pant silhouettes.

Balloon pants have recently been appearing frequently on runways and in fashion media as a new volume silhouette. If barrel jeans drew attention over the past few seasons as the signature curved pant, the balloon silhouette, which swells out more fully from the thigh down to the hem, is now widening its presence.

The trend of pant volume expanding in a bigger, more three-dimensional direction is clearly worth paying attention to.

Pant Silhouettes Are Getting Bigger

Barrel jeans and balloon pants may look similar, but their silhouettes give slightly different impressions.

• Barrel jeans: Defined by a barrel shape in which volume builds from the waist to around the knee, then narrows again toward the ankle. A structured curve is at the center of the silhouette.
• Balloon pants: A shape in which volume forms wider and rounder from the thigh down to around the hem. In many cases, they emphasize a fuller, more fluid volume than barrel jeans.

Recently, bottom silhouettes have expanded from slim fits to a variety of volumes, including wide and barrel. With balloon pants added to the mix, the ways of using pant volume are becoming even more diverse.

Names for closely related shapes, such as balloon, harem, and bubble, are sometimes used interchangeably, but what they share is a movement toward creating a relaxed, three-dimensional shape on the lower body rather than hugging it.

From SS26 to FW26

Rather than a one-off style that appeared in a single season, the balloon silhouette has been appearing repeatedly across multiple seasons.

Early Signal: SS25 Collections
Round, exaggerated bottom silhouettes appeared at Alaïa, Chloé, Loewe, and others, foreshadowing the volume pant trend that followed.

Spread: SS26 Collections
Balloon trousers appeared repeatedly at Michael Kors, Brandon Maxwell, Altuzarra, and others. Altuzarra in particular paired volume pants with structured shirts, showing a direction that also works as officewear.

Seasonal Expansion: FW26 Collections
The balloon silhouette continued into the fall/winter season. Jonathan Anderson presented balloon pants in Dior's FW26 collection, and full bottom volumes continued to be spotted at Chloé and many other brands.

The Balloon Silhouette Expands into Menswear: Celine SS27

Full bottom silhouettes, which had seemed centered on womenswear, are also being used in new ways in menswear.

At Michael Rider's first standalone Celine menswear show, held in Paris in June 2026, full pants that narrow near the ankle also appeared.

Celine placed soft, full pants beneath cropped jackets and sharp upper-body proportions. If balloon pants in womenswear have often been paired with bohemian or romantic moods, Celine's menswear translated them through a contrast between sharp tailoring and relaxed lower-body volume.

This case shows the potential for the balloon silhouette to go beyond a particular womenswear style and be used in menswear tailoring as well.

💡 Fashion Business Insights

Buyers: A New Option for Your Pants Portfolio
Balloon pants have been appearing repeatedly across multiple seasons, from SS26 through FW26 to SS27 menswear. You can keep your existing wide and barrel silhouettes while adding some balloon shapes to gauge consumer response.

Designers: What Matters More Than the Silhouette Is "How You Design the Volume"
Even the same balloon pants create entirely different impressions depending on the material, whether silk, poplin, denim, or wool. Rather than simply widening the pants, it's important to design together where the volume begins and gathers, how the hem is finished, and the proportions with the top.

Marketers: Show a New Styling Language Rather Than "New Pants"
Rather than emphasizing balloon pants on their own, it's effective to show them across different styling contexts, such as bohemian, officewear, and tailoring. The more unfamiliar the silhouette, the more content that visually suggests how consumers can actually wear it can lower the barrier to entry.
