"The costume is very adorable in person. The items on the jacket are attached with velcro. I am guessing it is for easy cleaning. The measurements are as follows: for the jacket (approx) Sleeve 15" Shoulder to shoulder 11" Shoulder to hem 17.5" Chest under arms Across 13" Waist across 13.25" Pants: Waist across Not stretched 7.5" Waist stretched 10.5" Outer seam 25" Inner seam 18" Hope this helps with your purchase."
