Trina Turk royal blue strapless dress size 2

Trina Turk size 2 royal blue strapless dress. Layered skirt. Tag says size 2 but fits more like a size 0 - see rough measurements in pictures. Feel free to ask questions. Great condition. Smoke free home. Came with belt but it has become discolored. I can include it if you want but dress can be worn without it.
