This is a deluxe Dustin costume from Stranger Things Season 4. It's a great disguise for boys, featuring a shirt with an attached faux t - shirt and a cap.

To wear this costume, first put on the shirt with the attached faux t - shirt. Then place the cap on your head. When you're done wearing it, take it off gently. For maintenance, you can hand - wash it in cold water with mild detergent. Don't wring it out too hard to avoid damaging the fabric. Hang it to dry in a well - ventilated area. Keep it away from sharp objects to prevent tears.
