Vintage garment sizes are not the same as those today (ie. a 50s/60s size 12 may be a 2/4 today). To ensure the best fit we suggest you measure your favorite similar style garment and compare to the measurements noted in this auction. Our measurements are taken while the garment is lying flat. We have doubled the waist, bust and hip measurements to reflect a more accurate measurement. Our measurements:SHOULDER to Shoulder: Measurement between either the shoulder seams or approximate shoulder width.BUST: Measurement straight across the chest (from underarm seam).WAIST: Measurement straight across the natural waistline.HIPS: Measurement straight across the hips (normally 5 - 7 inches below the waistline).LENGTH: Measurement from nape of neck or shoulder to hemline (dresses w/ straps are measured from shoulder).SLEEVE Length: Measurement from shoulder to cuff.SHOULDER to Waist: Measurement from nape of neck or shoulder to waist seam.SKIRT Length: Measurement from waistline to bottom hem.
