I have a vintage Butterick pattern # 6325 that features a fancy or prom dress in two lengths. The package contains instructions and patterns for the following:

• Dress, mid-knee or below mid-calf, has partially elasticized collar, close-fitting, lined, shaped front bodice, nside belt, princess seams, flared or tapered skirt and back zipper.
• A: shoulder yoke, above elbow sleeves with elastic.
• A, B: attached petticoat with ruffles and purchased ribbon.
• B, C: sleeveless.

This is a misses' 14, 16 and 18 and it is an out of production, uncut pattern - the package is showing some wear and it is priced accordingly. It is from a smoke-free home and shipping is free in the U.S.  Please check my other listings - I have many other patterns and will be glad to discount multiple purchases.
