Luxury Periwinkle Formal Maxi Halter Dress

I wore the dress one time to a wedding and it has been sitting in my closet ever since. I bought it brand new from a boutique. It’s in great condition and it’s very flattering on. I just have nowhere else to wear it to. It’s perfect for a wedding. It fit me perfect and I am normally a small, but this is an extra small. I am 5’6 135 pounds
