Frequently Asked Questions
How does bespoke sizing differ from made-to-order?
Bespoke is fully custom from a unique pattern; made-to-order adjusts a base pattern. Bespoke needs more measurements (14+) and posture data; MTO needs the standard 7.
Can customers self-measure for bespoke?
For 90% of fit, yes — with the right diagrams and a partner. For final fit (final sleeve curve, jacket length), an in-person fitting beats remote every time.
What's a bespoke suit's average fitting count?
Two fittings on top of self-measurements. Some master tailors do three. The calculator captures self-measurement data; you handle fittings in person or via video call.
Does this work for bespoke shirts too?
Yes. Shirts need fewer measurements than suits (8 vs 14). The calculator's product-type setting adjusts the form accordingly.
