Zara woman blue guipere lace dress

found this at a consignment store, didn't have the original slip, so I replaced it with a nude tone commando $90 slip. I will include it with the dress. there's a flaw that's hard to see in the arm detail in the back on the right. The stitching came undone so there's a gap. this is truly not at issue as I wore it like that, and nobody noticed. I only did upon close inspection. the knit work on this is stunning. fits more like a small.
