Physical clothing stores
We learned directly from customers how fit, handfeel and everyday wear shape the value of a garment.
We work alongside our partner factories to develop yoga wear for your brand.
It can show the shape you want. It cannot tell you how the fabric feels, whether the waistband stays comfortable, or what needs changing after the first fitting.
Bring us a technical pack, a few reference pictures or an unfinished idea. We will work through the fabric, sample changes and order details with the factory, while you keep one day-to-day contact.

Our story
In 2000, we were running physical clothing stores. Customers did not describe a garment in technical terms. They told us when a waistband rolled, when a fabric felt too thin, or when a piece still looked good after repeated wear. That daily feedback became our first lesson in product development.
From 2005, we began working with our own network of partner factories. We learned to translate what customers feel into the details a factory can act on: fabric, pattern, stitching, finishing and fit.
We entered traditional online foreign trade in 2010. In 2015, we formed an end-to-end export team so one group could follow an order from the first enquiry and sample discussion through production coordination and shipment.

Why Stellarisle
Over the years, we kept seeing the same gap: a buyer could have a clear product direction, while the factory still needed exact answers about fabric, measurements, finishing, quantity and timing. Stellarisle grew from that gap. We work as the overseas-facing team for our partner factories, keeping those questions in one conversation and carrying decisions from one stage to the next.
Our development
Each stage added a different part of the work we handle today.
We learned directly from customers how fit, handfeel and everyday wear shape the value of a garment.
Long-term factory relationships brought us closer to sampling, materials, construction and production.
We began bringing our product and factory experience to buyers through traditional online export channels.
A dedicated team began following enquiries, development, samples, production details and shipment.
One overseas communication window connecting activewear brands with the capabilities of our partner factories.
We work through the details with the factory: the agreed pattern, the sewing requirements and the checks your order needs.

The approved pattern and fabric direction guide the cut. Size breakdowns and material choices need to be settled before this stage.

Seams, measurements and finishing need checking against the agreed sample. We discuss the inspection arrangements with the factory.
A soft yoga set and a supportive training set need different discussions. We start with how you want the garment to fit and feel, your budget and the quantity you need.
A color reference, a measurement change or a logo position should not get lost between messages. We help turn your feedback into specific questions for the factory.
Sample costs, minimum quantities and production dates depend on the order. We discuss them with the factory rather than promise the same terms for every style.
Perhaps you are choosing styles for a first collection. Perhaps you already have a garment and want to change the fit. Tell us what you want to keep, what you want to change and what matters most.
Certificates & test reports
These are standards you may encounter when developing activewear. Tell us what your collection requires, and we will check the relevant documentation with the partner factory.

Quality management
A standard for an organization’s quality management system. It concerns how processes are managed; it is not a test result for a particular pair of leggings.
Ask which factory and site are covered, what activities are in scope and whether the certificate is current.
Read the ISO overviewTextiles tested for harmful substances
A textile certification focused on testing for harmful substances. The covered article and its intended use matter when reviewing documentation.
For a yoga set, check whether the selected fabric, trims or finished article are covered. Do not assume one fabric certificate covers every garment.
Read the official standardRecycled material and traceability
A standard addressing recycled material and chain of custody, with additional processing requirements. It is relevant when planning a collection with recycled-content claims.
Discuss the selected material and the documentation required for your order before agreeing on labels or recycled-content claims.
Read the Textile Exchange overviewSend your market, product and required standard. We can confirm what documentation is available and discuss any additional testing, cost and timing before production.
A reference picture, an estimated quantity and your target date are enough to start the conversation.
