The Pilates Opportunity: Building a Studio Activewear Collection for North America

In this guide

A reformer class puts clothing through an unusually revealing sequence: the wearer lies down, reaches overhead, folds at the hip and moves against resistance. A bra that looks secure while standing may shift during a side stretch. A shaped waistband can become uncomfortable when the body curls forward. For a studio buyer, those moments offer a more useful starting point than a photograph of a coordinated outfit.

Pilates deserves attention, but the evidence needs its proper boundaries. The 2025 ClassPass Look Back Report, covering January 1–October 10, 2025, identifies Pilates as its leading global booking category and reformer as its most-booked Pilates format. These are platform observations, not US or Canadian apparel sales.

Read the studio opportunity locally

There is tangible studio supply in both countries. Club Pilates’ international directory lists locations in the United States and Canada. A chain’s footprint shows access to one operator’s classes; it does not measure national participation or demand for an independent label.

For a founder, that distinction changes the research brief. Choose the neighbourhoods and studios you can actually serve, then ask what their members wear, how often instructors hear clothing complaints and whether the studio already sells apparel. A Vancouver reformer studio and a suburban US mat class may provide different purchase occasions even when both use the word Pilates.

Interview beginners as well as regular members. Experienced customers may already have strong preferences, while newcomers may need help understanding coverage and sizing. Record whether participants want a complete outfit, a replacement bra or an easy layer for the journey home. These are questions for local discovery, not assumptions about North American women.

Turn movement into a product brief

Low-impact exercise does not remove the need to assess support. Chest movement, comfort and coverage vary with the person, the class and the garment. Define the intended activity before choosing a marketing label. If a class includes faster transitions or standing sequences, include those movements in fitting.

Ask testers to perform an overhead reach, spinal roll-down, bridge and side-lying leg sequence. Observe strap movement, underband pressure and waistband folding. A fit session should allow private feedback: people may experience exposure or discomfort that they will not mention in front of an instructor or brand team.

Fabric selection should begin with a swatch and a construction specification. Fibre names alone cannot establish moisture management, opacity or stretch recovery. Compare candidate fabrics in the approved colours, both relaxed and stretched. If quick drying matters to the brief, request a relevant test method and result rather than copying the phrase from a product title.

Combination one: a shaped waist and a considered bra

UnimSport’s Ribbed Cross-Back Sports Bra presents a ribbed surface and crossed straps. It can be considered alongside the Crossover V-Waist Yoga Leggings as a proposed studio pairing. The purchasing question is whether texture and waist shape remain comfortable during the actual class, across the intended size range.

Check the bra’s strap junction against the back when lying down, and verify lining and pad construction on the chosen sample. Test the leggings’ front coverage when bending, the waist edge during repeated flexion and recovery after wear. This pairing is an assortment suggestion; the separate listings do not establish a packaged set or a tested high-impact support level.

Let coverage be a choice

Not every studio customer wants to train in a bra alone. Offer an option with more torso coverage and show it on bodies with different proportions. A cropped top can meet a high waistband on one wearer and leave a larger gap on another. Publish the garment length and model information that help a customer make that decision.

Lululemon’s Canadian Groove flared pant page illustrates how a retailer connects a silhouette with an intended activity and explicit inseam information. It is a retail presentation example, not evidence that a particular length or shape is preferred across Canada.

Combination two: a tank and a removable layer

For arrival and departure, review the intended layer over the selected studio top. Assess underarm coverage, hem movement and the combined fit through reaching and seated positions.

For buyers, the layer should earn its place through a clear use: walking between transport and studio, waiting before class or adding coverage afterwards. Test the zipper against the chin, sleeve mobility and bulk when carried. Do not describe it as weather protection without supporting evidence, and let customers purchase each item independently if that suits the retail model.

Build a size system before a colour story

A coordinated colour can disguise a poor fit strategy. Customers may need different sizes in the bra and leggings. Ask whether tops and bottoms can be ordered and sold separately, and establish how exchanges will work if the studio chooses to merchandise them together.

The size chart should distinguish body measurements from garment measurements. Include the measurement method, units and agreed tolerances in the buying specification. Do not translate an alphabetic size label into a universal US or Canadian numeric size without validation. Check the smallest and largest planned sizes, not only the development sample.

Choose colours after evaluating them under studio lighting and in photographs. A shade that looks attractive on a swatch can reveal lining edges or become uneven when stretched. Treat any preference for muted, bright or coordinated colours as a hypothesis to test with the studio’s own customers.

A studio can also help define how the garments will be explained at the point of sale. Prepare a short fit card for staff covering the intended activity, available measurements and any support limitation. Ask whether a member can try the item privately and how a size exchange will be handled. Clear staff information is especially useful when a customer is comparing a complete look with one replacement piece. Test the card during the pilot and revise questions that customers repeatedly misunderstand.

Approve a collection through evidence

Run a small fitting event with informed participants and collect separate feedback on comfort, coverage, appearance and intended purchase. Record the size tried and the movement that produced each issue. Compliments are useful design feedback, but they should not be counted as orders.

Before buying, resolve the remaining specification questions and agree which sample represents the final construction. Keep quantities tied to the studio’s actual customer base and available selling space. A strong Pilates collection begins with garments people can move in confidently and descriptions buyers can defend. Explore the linked UnimSport styles or discuss your studio requirements to identify the details that need confirmation.

Buyer Action Checklist

Define mat, reformer and mixed-format use separately.

Test straps, waist folding and coverage through a complete movement sequence.

Verify lining, pads, composition and performance evidence on the selected sample.

Confirm independent top/bottom sizing and measurement methods.

Test colour preference locally; separate interest from purchase commitments.
