Most activewear brands choose a fabric and a silhouette first and think about construction later. That order causes problems. Construction determines how the garment fits, how much it costs, how many pieces you must order, and what your design can and cannot do.
Three methods cover most activewear production: cut and sew, flatlock, and seamless.
Cut and sew
Fabric is cut into panels and stitched together. It is the most flexible method.
Best for: leggings, sports bras, tops, and jackets with paneling, color blocking, mesh inserts, pockets, or complex shaping.
Strengths: wide fabric choice, precise pattern control, easy to adjust fit between samples.
Trade-offs: seams add bulk and can rub if poorly placed.
Minimum order: from 200 pieces per style.
Flatlock
A specialized stitch joins fabric edges so the seam lies flat against the body. It is sewn rather than knitted, so it works with cut panels.
Best for: compression wear, base layers, and performance pieces where seam comfort and a clean athletic look matter.
Strengths: low-profile seams, durable construction, a recognizable sport aesthetic.
Trade-offs: needs stretch fabrics suited to the stitch, and fit details must be specified carefully.
Minimum order: from 200 pieces per style.
Seamless
The garment is knitted into shape on specialized machines, with little or no sewing.
Best for: sports bras, leggings, and tops where a smooth, second-skin feel and built-in textures or zones are the selling point.
Strengths: minimal seams, less material waste, distinctive knit patterns.
Trade-offs: design freedom is limited by machine capability, and fabric is created with the garment, so changes cost more.
Minimum order: the standard is 3,000 pieces per style across 3 colors. For a brand’s first order, we can start from 200 pieces per style across 3–4 colors; follow-up orders need higher quantities.

Sampling and sample fees
Samples are where construction decisions get tested. For cut and sew and flatlock, we refund 50% of the sample fee on production orders from 200 pieces and 100% on orders from 500 pieces. Because seamless requires specialized machines, we confirm capability before quoting a price or a timeline.
How to decide
Start with the product’s selling point. Smooth second-skin feel points to seamless. Complex design points to cut and sew.
Match the method to your quantity. If you are testing a first collection, cut and sew or flatlock offers more room for fit changes.
Check your budget per unit. Seamless and complex cut and sew garments are not priced the same, so share your target price early.
Confirm your timeline. Construction affects lead time as well as cost.
