If invited to someone's house for dinner, lateness (over 10 minutes) is seen as a discourtesy.
Shoes are always removed before entering the house and a gift for the host, such as a bottle of wine or a bunch of flowers, is well received.
Shoes should be removed when entering someone's home. Shaking hands is customary as a greeting and guests are expected to refrain from drinking until the host or hostess toasts their health with kippis (Finnish) or skål (Swedish). When toasting, make eye contact with everyone around the table, and take a sip of your drink; shots of liquor are not expected to downed all-in-one. Do expect your glass to be refilled frequently by the host or hostess.
Most Finns prefer practical, casual clothing, except for special occasions. ‘Alternative’ fashion, piercings and tattoos are popular among younger Finns; not surprising for a country where heavy metal bands top the charts regularly.
Although renowned for their liberal attitudes, Finns can appear to be rather reserved with strangers, so do not be alarmed if conversations start slowly. This sense of composure will often disappear after a few drinks, or in the sauna.
