The dress has movement and visual softness, floats without cling, and skims hips gently rather than clings.

Start My Dress

Started in Sammamish, Washington

A small company making custom dresses more personal

Build-a-Dress began in 2025 in Sammamish, Washington, with a simple question: how could we make ordering a custom dress easier for the person who will wear it?

We started with a laptop and a few dressmaking partners. Our goal was to help customers turn an idea into a clear design, understand what it would cost, and get help managing production.

You choose the details. We help you understand your options and guide your dress from the first idea to the finished piece.

Plan your budget

How Much Does a Custom Dress Cost?

Custom dresses start at $650. These ranges can help you plan, and you can review an estimate for your own design before ordering.

Planning range

Prom, formal & modest dresses

$650-$1,500+

Fabric, skirt volume, lining, bodice support, and beading affect the price. Simpler construction can help keep your design within your budget.

Planning range

Wedding & quinceañera gowns

$1,250-$3,250+

Full skirts, structured bodices, long trains, lace, and handwork can add materials and production time. Intricate gowns may exceed this range.

Start Designing

What else should I budget for?

Review the fabric, lining, construction, embellishments, measurements, delivery date, shipping, taxes, and fees in your order. AI generation credits are separate from dress production. Leave room for accessories and any local alterations.

How long does delivery take?

The process typically takes 2-3 months from order confirmation to delivery: 1-2 weeks for design finalization and measurements, about 5-7 weeks for production and quality review, and 1-2 weeks for shipping. Confirm the current delivery estimate before paying and leave extra time for a local finishing alteration. Complex handwork and peak-season demand can extend the timeline.

We currently deliver to addresses in the United States. Allow 1-2 weeks for shipping within the overall 2-3 month order timeline. Review the delivery estimate and shipping charges for your order before paying.

Will I need a final fitting?

Use our measurement guide and provide the measurements requested for your design. Your dress is made to those approved measurements; a local finishing alteration may still be needed for personal preference or body changes. Leave time and budget for that fitting. Contact support if the delivered dress materially differs from the approved order, under our refund policy.

Buyer Protection Guarantee

Our team reviews your order, coordinates production, and helps resolve defects if your dress arrives materially different from the approved specifications.

Full refund if your dress arrives defective, damaged, or not made to your specifications

What if I need changes to my formal dress design?

Refine your design before ordering and confirm the fabric, construction, and measurements before production.
