NWT Vintage Express Camisole. Sized XS see measurements for size

wow!! Gorgeous cream camisole by Express. Vintage with attached tags. It is polyester with nylon lace trim. The straps are adjustable. Machine washable and tumble dry. The measurements are taken laying flat and are approximately 16-1/2" under bustline 18" across the bottom. The measurements are larger than an XS size. I believe it was mislabeled, and that is why it is unworn. This is a thicker, more luxurious feeling fabric and could easily be worn alone
