Why the conversation usually fails
You know what you want. You can picture it. But a dressmaker needs it in a specific order, and a photograph on a phone answers almost none of their questions. They cannot see the back from your screenshot. They cannot tell whether it is lined. They do not know how long you want it on your body.
The order they think in
Describe a dress in this sequence and you will sound like you have done it before:
- Silhouette — the overall shape. A-line, sheath, fit-and-flare, mermaid, ball gown, column.
- Neckline — sweetheart, square, V, scoop, bateau, halter, off-shoulder, strapless.
- Sleeve — length first, then shape at the wrist: fitted, tapered, straight, flared, bell.
- Waistline — natural, empire (under the bust), dropped, or basque (pointed at the front).
- Length — not "midi" alone. Say where you want the hem to land on you.
- Closure — invisible zip, buttons, or pull-on.
- Lining — fully lined, bodice only, or unlined.
Say those seven things and a dressmaker can picture and price your dress. Say "something like this but a bit different" and they cannot.
What to bring
Bring a printed specification if you have one. Otherwise: two or three reference images including at least one back view, a garment you already own that fits well in the area that matters most, your fabric or a swatch, and your deadline. Say your budget out loud — makers would far rather design to a number than quote something you were never going to accept.
Things worth asking for explicitly
Pockets. A hem you can actually walk in. Sleeves that let you raise your arms. Bra-friendly straps. None of these are assumed, and all of them are easy if mentioned before cutting and expensive afterwards.
