Frequently Asked Questions
How do I know how much to shorten my dress?
During checkout, you can select from three easy ‘Measurement Methods’. If you don’t have exact measurements, we highly recommend putting the dress on with the shoes you plan to wear, folding the hem to the desired length, and securing it with safety pins. You can then simply select “I’ve pinned or chalked the mark” in our builder.
Do I need to send photos of the dress?
Yes, our booking form asks you to upload up to 3 photos (front, back, and a close-up). Because dresses come in so many styles (pleated, lined, A-line), seeing a photo helps your assigned tailor understand exactly how to approach the hem before your item arrives.
Is the return shipping safe for delicate items?
Absolutely. Once your assigned professional tailor completes the expert alteration, your tailoring item is carefully packaged and shipped securely back to your address with full tracking.
