My son just turned 8 (dress size 134) could wear the costume just as yet. The trousers were clearly too short! Might just as still fit at 128. So we pulled underneath a normal schwaze pants. Was OK since then the strange "shoes" (sewn right on the costume) did not have to be worn. The downside is unfortunately the mask. She looks visually quite good. You can look through good and you get good air. BUT: fell down again, she immediately cracks. The material is too hard and is apparently under tension, so that the smallest shock results in cracks. So be careful in.
