Wear it & Trash it!

A Seersucker Blue/white Sack with just an interesting heathery mid-blue polo shirt underneath is lovely.
Cordo woven belt.
Pale-ish Khaki chinos worn with an Ivy break-that-is-barely-a-break...
No socks!
Old Cordo Penny Weejuns.

(Or do the sockless Buck look - Who's gonna stop you?)

My new crop is No.6 on top & No.4 at the sides & back. Side parted with squared-off slight sideburns.

Walking around I like to hear "So Tired", Art Blakey & The Jazz Messengers, in my head:

One day I will get run over...

Sounds very plausible.
They were originally very cheap items - Seersucker suits were too. Worn by the rich and poor just as a cool Summer item.
Can't imagine anybody making a fetish out of such a lowly item back in the day...

staying for a day in London is like dream come true.I have never visited it but since long I desire to visit that place of my dream.So,How was your trip? Which are the places of attraction there?

Wow talk about a blast from the past.
