- The cupped LEGO gloves make it hard to hold candy bags or phones; keep them easy to slip off when needed.
- Wear comfortable sneakers in a matching neutral color like black or dark grey to blend in with the pants.
- If DIYing, use lightweight foam board instead of heavy cardboard to keep the boxy tunic comfortable for hours.
