Boxer Briefs Tech Pack Development

Currently, I am working on designing a line of boxer briefs and need to create a comprehensive tech pack. These aren't your run-of-the-mill boxer briefs, though. They need a hidden pocket incorporated in the design intended for wallet storage. The primary fabric for these boxer briefs should be cotton.

Ideal candidates for this job should have:
- Profound experience in fashion design and garments construction is necessary.
- An understand of textile properties, specifically with cotton.
- A knack for innovative storage solutions in clothes.

Your objective is to translate my vision into detailed, clear instructions for the manufacturers. Please include examples of relevant previous work in your proposal. Make sure your bid reflects your knowledge of creating tech packs, designing boxer briefs, and accommodating hidden pockets in the design. Coming up with solutions for potential manufacturing hitches will be a big plus!
