NWT J. Crew striped strapless dress!

Super cute summer dress!! I bought it for a graduation party, but decide not to wear it. It fits like an average size 4 and has elastic along the top to help keep the dress in place (see 2nd to last photo). It is 100% cotton and comes new, with the tag! The zoomed-in image of the zipper shows the color most accurately. The stripes are light blue and off-white (not white or cream).
