i have worn this dress 3 times, once for a full day wedding, so it has been worn but it has no flaws except one small pull I found and put a picture of some stitching of the embroidery going over a seam on the waist but it is truly unnoticeable I just was trying to be very thorough, it may have always been there as it is in the embroidery and not the seam. it's a beautiful dress. Fabric is a lightweight cotton viscose, i would not call this quite semi sheer but if the light hits in a certain way the skirt can have some light through it but not enough to be semi sheer or need a slip in my opinion.
