I am fan of overall dress and find this really cute and especially attracted to the buckles design. Couldn’t decide which size so bot .. S and M. I m 158cm tall 53 kg, S is fit- baggy; M is loose- baggy for your reference. I recommend this item though I may have to return because .. is just kinda of too young for me.😞sad. Yet I really like this overall otherwise I would not have buy 2 diff sizes in one order .
