Custom Garter Belt With Six Suspenders

I need a skilled garment maker to build a purely functional garter belt that will hold heavy-duty medical compression stockings all day. The belt must sit high on the waist and be noticeably wider than standard lingerie styles to spread pressure comfortably.

Core specs
• Fabric: black elastic, firm yet breathable
• Width: extra-wide waistband (we’ll finalise the exact measurement once you see my sizing)
• Suspenders: six individual straps, each fully adjustable, ending in strong stocking clips that will not pop open under tension
• Closure: Velcro at centre back or side for quick on/off and micro-adjustment
• Overall look: utility first—no decorative lace or trim needed

Your task is to source the materials, construct the belt, and ship the finished piece to me. If you already work with industrial sewing machines, elastic webbing, and metal/plastic suspender clips, this should be straightforward. Please let me know:

1. What grade of elastic you would use for the waistband and straps.
2. The clip style you recommend for thick compression hosiery.
3. Estimated turnaround time and shipping method from your location.

I will provide my exact waist, hip, and stocking length measurements once we start. Photos during production are welcome so we can confirm fit details early and avoid rework.
