This dress includes a nude bodysuit inside. V-neck opening on front and back, embroidered with different sized pearls. Fitted skirt with train, lined with crepe silk satin and topped with gathered crepe georgette silk. Pearl buttons closure at mid back. In regards to alterations, I just had dress hemmed at the bottom. I absolutely loved this dress and received so many compliments. When I went to try this on in store, there were at least 3 other girls and everyone looked great in it! It is very comfortable dress; you will be able to dance all night!
