Both items have been worn less than three times and are in beautiful condition. I also wore them for a formal occasion for a safe childbirth prayer! I think you can wear them until autumn if you pair them with a cardigan. I wore a size S for the top to prevent the sides from opening. I usually wear sizes S-M, but the pants can be adjusted with a drawstring, so the fit was just right without being too loose. - Brand: UNIQLO - Size: S (Bust 77-83cm) - Color: Black - Style: Pant Suit Set - Material: 95% Polyester, 5% Polyurethane Thank you for looking.
