Rubie's Official Disney Star Wars Darth Vader Classic Child Costume, Kids Fancy Dress

Is this suitable for a 5 year old

can you plesae tell me the corretc size for a 114cm child

What’s the size for a 13-14 year old -would it fit a 5’8” boy?

My 3 1/2 year old is small, wonder if I could adjust this outfit or if it'll just swamp him, by the sound of things, the sizes are large
