How to Write a Sports Bra Sourcing Brief That Gets Accurate Quotes

A quote is only as good as the brief behind it. Send a paragraph describing a medium support sports bra to three factories and you will get three numbers spanning a wide range, none of which you can compare, because each factory filled the gaps with a different assumption. The factory that assumed the cheapest fabric wins the comparison, and you discover why at the fitting. A complete brief takes an hour to write and removes most of that risk.

Describe the construction, not the concept

State the silhouette and how it is built: racerback with straps converging into a vertical center panel, cut-out back panels, elastic underband with a three-row adjustable hook closure, removable pads, four-way stretch shell. Add the seam construction you expect, flat seaming through the band for example, and the cup range the block is engineered for, such as B and C with a separate extension above that. Every one of those items moves the price, and leaving them out means the factory prices something else.

Give a fabric target, not only a handfeel

Soft and stretchy is not a specification. Give fiber composition, weight, stretch and recovery expectations, and the finish you require. If you do not have a fabric selected, say what the target is and ask the factory to propose a specific quality with mill reference, weight and price. Then compare proposals on the named fabric rather than on a total. This single item accounts for most of the spread between quotes.

Quantify the order properly

State total units, units per colorway, and the size breakdown. Minimum quantities usually apply per color and sometimes per size, so a 3,000-unit order across eight colors prices very differently from the same 3,000 across three. If you are planning a repeat, say so and give the expected annual volume, because that changes how both parties think about tooling and fabric booking.

Include testing, packaging and delivery

Name the tests you will require and who pays for them, the packaging specification per channel, labeling and barcode requirements, the incoterm and port, and your required delivery window. Each of these is a real cost line. A quote that excludes inspection and testing is not a lower quote, it is an incomplete one.

Send a reference sample and state what is negotiable

A physical reference removes more ambiguity than any amount of description. Send one, mark what must match exactly and what is open to suggestion, and ask the factory to quote alternatives where it has a better idea. Finally, send the brief once, complete, to a shortlist rather than adding requirements over several emails. Factories price uncertainty, and a brief that grows while they are costing it produces a padded number you then spend weeks negotiating back down.
