We are happy to hem a dress for you! We will need 2 measurements from your waist to the spot you would like the hem to fall, one measurement in the front, and one in the back(It is not uncommon for these 2 measurements to be slightly different.) We will also need the measurement from the bottom of your armpit to the spot you would like the hem to fall. When taking these measurements, stand straight, looking forward, and have someone else do the measuring. Also consider the shoes you will be wearing. Please keep in mind that any alterations we do on any dress renders that dress non-returnable, non-refundable.
