Beautiful dress appears to be handmade - fully lined.  The fabric is a shiny satin type fabric with a metallic yellow gold embroidery detailing.  I will provide full measurements.  There is also a scarf included - also fully embroidered and beautiful.

Bust measures from armpit to armpit 18".
Waist (or seam under the bust running vertically) is 17" from side to side.
At the widest point of the dress - or the hips - it is quite a bit wider as the dress flares out at the waist - I measure a 26"at the widest point from side to side.

Sleeves are 18" long (3/4 sleeve)
Across the back from shoulder seam to shoulder seam is 15".

Length from back of dress to bottom of dress (in back) is 57".
From front of dress to waist line is 11".   The bust area does have darts for a form fitting look.

The scarf is 21.5" wide and 59" long.

If you have any questions please feel free to ask them.  This is beautiful - not perfect as I do see a few loose threads in the gold embroidery - also has rhinestone accents.
