my daughter wore this once for her birthday party when he was 4 . we kept it as dress up for a little bit . chest flat lay measurements is 10 inches . elastic on back and halter strapsare ribbon . the straps came loose from the sequin top and i sewed them back on so they are actually reinforced now and shouldn't come loose . you cannot tell by looking at it . the unicorn horn on the front also came loose and i glued it back together. $27 new on amazon . this does not include any headband . just the dress
