The Louis Verdad BLACK Satin Thick Dress is marked a size Small however, this is very tiny and is more XS.  Please review the approximate measurements below. This would fit a Size XS, 0 or 2 sized lady.  
It is a stylish and sophisticated option for various formal occasions. The midi-length dress features a flattering v-neckline, short cap sleeves, and a button closure that buttons on the inside so the buttons don't show for added elegance. The ruffled accents and belted waist add a touch of charm to this timeless designer piece, suitable for all seasons. Made from luxurious satin fabric in a classic black color, this dress is a versatile addition to any woman's wardrobe. I could see this with white elbow gloves, a white and black wide brim hat and simple black pumps.  Absolute Royalty!  Or for the towns dance night contest with your hair done in a 50's style.  It's beautiful! Though this is Vintage and not without it's flaws.  

There isn't much stretch to this so you have to be tiny and that's a 2 or less.  There is a run just under the waist that I steamed but would need more careful steaming.  The piling is in the back near the darts of the skirt or flowing part of the dress.

Approximate Measurements Please review to ensure fit.  I'm not a seamstress but know this is very tiny.
Shoulder to Shoulder: 13"
Pit to pit: 17.5 (There is no button here at the top.  Maybe women were more busty or they put all in front.)
Waist (8 inches down)  14"
Length from mid of collar seam: 37.5"
Length of Sleeve - 6"
Opening of Sleeve- 6" 
Center of Back to shoulder Seam - 6.5"

Condition Notes: There is some piling in the back.  Because of the satin skin of this dress I didn't want to even try to mess with it and making it worse.  See last 2 pics.  Please review all photos provided and the approximate measurements as this runs small.
