What branding details should I prepare for private label underwear?

Short answer: Private label branding covers everything that carries your name or required information: the logo and its colours, the waistband, sewn or printed labels, hang tags or inserts, packaging, barcodes and the carton marks. Delays usually come from missing vector files, colours given only as screen colours, label text that has not been checked against the rules for each market, and barcodes that are not ready. Prepare vector logo files, colour references from a physical colour system, waistband artwork with repeat size, approved label text for each market, packaging artwork, one GTIN per size and colour, and carton mark instructions. Send them together with the tech pack, and approve physical samples of each item before bulk.

Logo and colour

• Vector logo files, such as AI, EPS or PDF with outlined text.
• Colour references from a physical system the factory uses, plus a physical standard if colour is critical.
• Minimum size and clear-space rules.

Waistband

• Logo artwork at the repeat length the elastic supplier uses.
• Elastic width, colour and construction, such as jacquard or printed.
• Placement relative to centre back.

Labels

• Size, fibre composition, care, country of origin and company identity for each market.
• In the US, fibre, origin and identity rules are in 16 CFR Part 303 and care rules in 16 CFR Part 423.
• In the EU, fibre composition under Regulation 1007/2011, in the required languages.
• Label type: woven, printed or tagless, and placement.

Packaging and tags

• Box, sleeve or bag artwork with dieline.
• Hang tag or insert card artwork, if used.
• Any warnings required by sales channels.

Barcodes

GS1 guidance is that each size and colour combination needs its own GTIN. Prepare a barcode list matched to style, colour and size before packaging artwork is finalised.

Cartons

• Carton marks: brand, style, colour, size breakdown, quantity, carton number.
• Any retailer or warehouse label requirements.

Approvals

• Approve waistband, labels, packaging and barcodes on physical samples.
• Keep an approved artwork master with version numbers.

A practical order of work

Start with the logo and colour standards, because waistband and packaging suppliers need them first and have the longest lead times. Then finalise label text once fabric composition is confirmed, prepare the barcode list once sizes and colours are fixed, and finish packaging artwork last. Sending everything in one organised folder with clear file names saves several rounds of questions.

Limits

Requirements differ by market and retailer. Check current rules and buyer manuals.

Facts, recommendations and uncertainty

Established: private label branding includes logo, waistband, labels, packaging, barcodes and carton marks, and labels must follow market rules. Recommendation: send a complete, versioned branding pack and approve physical samples. Uncertain: retailer-specific requirements.
