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 a 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.
