I ordered my sons size and when it came in it was too small. He already saw it so naturally I just let him keep it but it stinks knowing I’ll have to buy another suit already because he can’t wear his out.I am in love with these! My son's eyes lit up when he saw them!!! They fit just right. He's a size 2T & slender.It was a hit with my nephew! We bought it for his birthday, and he wore it to his swim party.My grandson loves this suit. He’s 2 1/2 And it’s perfect.Like it so much, great quality and very beautiful, lovely puppies!!! A little large...That my lil son was so happy to see them...Puppy Dogs favorite for grandsonPerfect my son loves them
