Gosh, I'd forgotten all about the old Blacker/Gee thread, but it ties in with much that I've been mulling over of late - and that wonderful ''Yale' In 'Manhattan'' thread that made a brief comeback a few weeks ago. 
I wasn't heartbroken to note the darting on the Blacker tweed jacket that turned up this morning.  I'd just rather they were absent.  Not, of course, that any woman is going to look at them twice - she'll just see (if she bothers to look) a man with shortish grey hair wearing a tweed jacket.  An old man look?  Perhaps - but, more to the point, a non-threatening look, especially if the jacket is accompanied by a button-down, flannels, PTBs or wingtips.  Overcoat folded carefully over one arm.  It looks, well, mild.  It does not look 'Mod'/'peacock' or anything like.  Who once talked about 'frump'?  TRS did.  Think Clark Kent...  think 'Yale'...  think tortoiseshell rims, off-white hosiery, easy charm (for both genders).  Think kindness and consideration.  Then a woman might not mind getting into a railway carriage with you. 
She might even give you her number.
