A princess line dress incorporates a classic A-line bodice with a full, floor-length skirt. Princess line gowns are excellent for creating the appearance of a thin, long waist, and make popular wedding dresses and other special-occasion wear. In order to create an accurate princess line pattern, be sure to carefully measure the client in advance and prepare the pattern one size larger and one size smaller than the client's measurements.
Place the interfacing onto the pin board and pin it into place.
Sketch or trace an A-line bodice. Most necklines in princess line gowns are either sweetheart or V-line, so determine which of the two the client desires and sketch it appropriately.
Ask the client what her preferred sleeve length and style is, and sketch it onto to interfacing as well. Common sleeve types for princess line dresses include full- and half-bell sleeves, puffed-short sleeves, or if desired, sleeveless.
Sketch the skirt onto the pattern. Princess skirts typically contain three times the fabric of a regular skirt at the bottom. The fabric is slowly reduced until it matches almost equally to the waist.
Cut out the pattern pieces and pin them to the manikin. Adjust the pieces as necessary accounting for seam allowance, lace attachments and darts.
Show the pattern to the client, and with their approval draft one size above (2-inches greater) and one size below (2-inches less) the original pattern.
