Seido High diamond whites—baseball uniform cosplay in S–XXXL with measurement fields for chest and waist. The Ace of Diamond Seido High Baseball Uniform Cosplay Costume is sports-anime ready.
Sizes
S–XXXL plus height/chest/waist/hips fields.
Throwing room
Pitching poses need sleeve and shoulder clearance—size up or enter chest numbers if muscular. Between letters, take the larger. Hand measurements can be off by 1–3 cm.
Diamond tips
Halloween and sports-anime cons suit Seido looks. Soft cleats or sneakers. Match letter size, fill fields when broad-shouldered, and keep numbers readable for team photos.
