Trying to identify a book I used to love as kid. All I can remember about it is that there were two really tall couples, two sisters who married two brothers I believe (but all were extremely tall and lanky). I want to say it was set in the Edwardian period (or thereabouts) as the men were dressed like Edwardian dandies and I think they had handlebar mustaches (a la Edward Gorey). I believe the women were dressed in Edwardian white lace dresses and may have been wearing those Edwardian straw boater hats. This is really all I can remember about it; while I doubt this will be enough to go on, I figured I’d give it a shot. Thanks
