In predominately Buddhist countries we ask that you dress respectfully and avoid very short shorts / skirts and singlets / tanktops when visiting temples or other holy sites. (tripcentral.ca)
Everyone wears tanktops, the official bro uniform. (film.avclub.com)
For a camisole on top I choose any old tanktop wich is a bit higher on the chest (or I wear it back to front) and wider straps. (40plusstyle.com)
