The Cohen brothers Isadore, Lou, and Irving run a
second-hand clothing establishment near Covent Garden (cf. the
Moses Brothers in Ukridge's Accident Syndicate, and the real-life Moss Bros. of
Covent Garden, mentioned in Service With a Smile).
In The Magic Plus Fours (where the
first brother's name is spelled Isidore) they sell Wallace
Chesney a pair of prismatic Plus Fours allegedly made for
Sandy McHoots. In Sam the Sudden they sell ready-made clothing and
outfit Sam Shotter in a bold tweed suit. In The Ordeal of Osbert Mulliner they outfit
Osbert Mulliner in secondhand traveling clothes. In Joy in the Morning
they supply Bertie Wooster with a Sinbad costume. In Frozen Assets,
they are called on to supply trousers for Biff Christopher.
