Well maybe not quite his, which I believe is Italian and rather pricey for what it is...
But the shape & drape of it suits my mood today- sloppy, slouchy, no shoulders...
I could do something similar teamed with a semi-ironed OCBD and last night's Bills. Maybe stick on some Camp Mocs too & be done.
A really sacky sack for the summer could be fun.
Wore my Olive Poplin this morning, but wore it with a less than obsessive press to it... All this is new to me & I'm really quite enjoying it. Rumpled Ivy seems to suit the organic slope of the shoulders rather well. Next I'll have to stop my manic shoe polishing...
I'm getting there...

Any thoughts on the Larry David Trademark Jacket?
Yes, it's a sloppy rag - that's the point!
