Swimwear Glossary

Plain-English definitions of the terms used in swimwear development, materials, production and shipping.

Sourcing swimwear comes with its own vocabulary. Use this glossary to check a term before you brief a factory, compare a quotation or read a specification. Where OYOYI uses a term in a specific way, the definition says so.

51 terms

A

Adjuster

A small piece of hardware, usually metal or plastic, that lets the wearer change the length of a strap.

See:Trims & Packaging

AQL (Acceptable Quality Limit)

A sampling standard used in inspection. It sets the maximum number of defective items that is considered acceptable in a random sample, so a batch can be accepted or rejected without checking every piece.

See:Quality Control & Inspection

B

Bonded seam

A seam joined with heat-activated adhesive tape rather than stitching, which gives a flatter, smoother finish.

Bulk production

Full-quantity production of an order, started after the sample has been approved.

See:Production Orders

C

Care label

A label sewn into a garment that states its fiber content and care instructions. Requirements differ by market.

See:Trims & Packaging

Chlorine resistance

The ability of a fabric to keep its color, shape and elasticity after repeated exposure to chlorinated pool water. It depends on the fiber and construction, and needs test evidence rather than a fabric category name.

See:Testing & Compliance·Material Sourcing

Colorway

A specific combination of colors in which a style is offered.

Commercial invoice

A document that states the goods, their value and the parties in an international shipment. It is used for customs clearance.

Compression fit

A close, firm fit designed to hold the body in place. It is common in competitive and athletic swimwear.

Cover-up

A garment worn over swimwear, such as a beach dress, shirt or wrap.

D

DDP (Delivered Duty Paid)

A shipping arrangement in which the seller pays shipping, import duties and taxes, and delivers the goods to the buyer's destination. Under other arrangements, duties and taxes are usually paid by the buyer. Confirm the terms before ordering, and tell us in advance if you need DDP.
