Sonia Rykiel dressy event separates

Like new condition. Worn for an event. Sequined viscose/rayon and wool racer tank with sheer panel at natural waist. Tank has identical sequined back. Loose fitting wide leg pant with front and rear pockets. Pants are very slinky and an almost sheer texture. I don’t feel they were see though when on. Sized European 42 I feel they are closest to a size 12. Made in Italy
