MOST Dresses at Pearl & Lulu's are Vintage Dresses, Vintage Dresses & Vintage Sizes, can differ greatly from today's typical sizes. This is mostly because in the earlier decades of the 20th century regulations on sizing did not exist! So a vintage Size 10, can often fit like a Modern Size 2. For the convenience of my buyers, I always attempt to provide complete measurements of garments in my listings. The measurements of the garments are done so that you may compare something similiar of your own... They are done seam to seam, to get the circumference measurements the measurements should be doubled when applicable (If you are comparing to your personal measurements rather than measurements of a garment). This is the best way to get the best fit. If you are still unsure if the garment will be a good fit for you, send me a message!! I am always glad to help in any way possible to make this an easy and pleasureable buying experience... Thanks!
