(Portland, OR)  --  Oregon's last Brooks Brothers store is no longer in business.  The chain known for its button-down look and classic suits has closed its downtown Portland location, citing "national trends."  A Galleria spokeswoman told "OregonLive" that it's more likely the company concluded their line wasn't a good fit for the city.  She says Portland is "more tech, casual stuff" than the clothing Brooks Brothers offers.
