"My son is so excited about wearing this on Halloween!! He put it on and wanted to wear it all night! The fit is perfect! He is a size 7/8 in jeans and is tall for his age. The size Med. 8-10 we ordered fits him really good!! It is not tight on him and not too big.. He has room to move around. The quality of this costume I would say is great for a costume, the padded muscles are great making it realistic! He will match his little brother being Batman!! Can't wait!!"
