Working With Swimwear

The team includes experienced:

• Swimwear pattern cutters
• Garment technologists
• Sample machinists
• Tech pack designers
• Fashion manufacturing consultants

This practical manufacturing experience allows them to provide real-world guidance on:

• Swimwear startup costs
• Sampling and production budgeting
• Fabric sourcing
• MOQ planning
• UK vs overseas manufacturing
• Production-ready tech pack development

The studio works with:

• Startup bikini brands
• Sustainable swimwear labels
• Luxury swimwear collections
• Active swimwear companies
• Resortwear brands
• Ecommerce swimwear businesses

Their services include:

• Swimwear tech packs
• Bikini CAD drawings
• Pattern cutting
• Sampling
• Grading

Real Manufacturing Knowledge For Startup Brands

Many first-time fashion founders underestimate the true cost of launching a swimwear line. Based on their experience working with startup brands, The London Pattern Cutter’s manufacturing team highlights that sample revisions, fabric sourcing, technical development, and marketing are often the largest hidden expenses in early-stage swimwear businesses.

The company also advises new brands to begin with:

• Smaller production runs
• Limited colourways

• UK sampling before overseas manufacturing

This approach helps reduce upfront risk while improving product quality and factory communication.
