I purchased this from the overseas site Q10! I have never worn this item! I bought four of these with different patterns, and I've worn two of them. They are very durable, so I'm selling the remaining two! I wear them comfortably except in the peak of summer! They have wrinkles because I stored them in a garment case! They are machine washable, so please wash them once before use! BT21 blue and white striped pajama set with RJ illustrations, made of smooth, comfortable material. Long sleeves, long pants. - Brand: BT21 - Color: Blue and white stripes - Design: RJ illustration - Type: Pajama set - Style: Button-up shirt - Pants: Elastic waist Thank you for looking.
