The Spec Sheet: What a Bodysuit Actually Needs
A bodysuit is not a t-shirt. It is a foundation garment under structural tension, and its spec sheet needs to reflect that. The critical measurements go beyond chest and waist. You need crotch depth, the distance from the waist to the gusset center, because if it is off by half an inch, the garment rides up or sags. You need the snap tape spacing at the gusset, because mismatched snaps mean the closure fails under stretch. You need the elastic width and tension at the leg opening, because too tight leaves marks and too loose means the leg gaps when the wearer sits. The fabric spec must include weight, stretch percentage, and recovery rate. A four-way stretch knit with 40% stretch but only 60% recovery will bag out at the knees and elbows by lunchtime. The seam spec should call out stitch type, four-thread overlock for side seams, coverstitch for hems, and whether the factory uses a flatlock or a lapped seam at the gusset. Each of these details is a line item in a tech pack, and each one is a point of failure if left to the factory’s discretion.
Minimum order quantities for bodysuits run higher than for simpler garments because the construction is more complex. A factory cutting t-shirts might offer a 300-unit MOQ, but bodysuits, with their gussets, snap closures, and elastic applications, often start at 500 to 1,000 units per style and color. The reason is not greed. It is setup cost. The cutting markers for a bodysuit are more intricate, the sewing line requires more stations, and the quality control process takes longer because the garment has more failure points. A factory quoting a 200-unit MOQ on a bodysuit is either absorbing the setup cost into the unit price or cutting corners on construction. Neither is sustainable. For a buyer testing a new style, the path is to negotiate a first run at the lower end of the MOQ range, 500 units, with a commitment to a second run at a higher volume if the style sells. That gives the factory a reason to invest in the setup and gives you a way to test the market without overcommitting.
The Questions That Separate a Factory From a Partner
When you have a tech pack in hand and a list of potential factories, the conversation shifts from "can you make this?" to "how do you make this?" The answers tell you everything. Ask about their snap tape supplier. A factory that sources snap tape from a name brand, like YKK or a comparable mill, is building to a standard. A factory that says "we have a local supplier" is building to a price. Ask about their elastic testing protocol. A factory that can describe a wash test, where the elastic is stretched and released over a set number of cycles, is thinking about durability. A factory that says "we check it by hand" is hoping for the best. Ask about their color management. A factory that uses a spectrophotometer to match dye lots is producing to a tolerance. A factory that matches by eye in a warehouse is producing to a guess. These questions are not about catching a factory in a lie. They are about understanding their process, because their process is your product.
Even with a perfect spec and a vetted factory, the first production run will have issues. The fabric may arrive slightly different from the sample, a seam may need to be moved, or the fit may need adjustment. This is normal. What matters is how the factory responds. A partner factory will document the issues, propose solutions, and revise the tech pack for the next run. A transactional factory will argue, blame the buyer, or disappear. The first run is not the finish line. It is the first draft of a production relationship, and the goal is to end it with a revised spec that makes the second run flawless.
The Path From Sample to Sellable
The buyer in Los Angeles eventually found a factory that produced to spec. They started with a 500-unit run, documented every measurement, and used the first run to refine the fit. The second run, 2,000 units, came in clean. The difference was not the factory. It was the spec. A bodysuit manufacturer can only build what you define, and the definition lives in the tech pack. The sample gets you in the door, but the spec is what gets you to the shipping dock. The factories that can work to a detailed spec are the ones that turn a design into a business, and the buyers who learn to write those specs are the ones who do not end up with a warehouse full of returns. The work is in the details, and the details are in the document.
That is the whole of it.
What to send us
If the specifications above match what you are sourcing, send your tech pack to Orange Sea Clothing. If the pack is not written yet, sketches and a reference sample are enough to start — sample development covers the design review, fabric and trim sourcing, pattern making and the first prototype, so you see fit and construction before you commit to a production run.
