My daughter (3) usually wears size 104. Based on the reviews, I ordered it in size 116. Only at home I have found that 116 not 116, but 110/116 means. He also looked quite small but suited amazingly perfect. When the carriers it has even some leeway without her slip. He looks very cute from, she's running around all day at home and wanted him not back off (that seems to be comfortable). So value for money also seems to be true, but I must say that he has not been tested in the water from us. But so far I can only recommend it and would buy it again.
