I have several:
My first H&K shirt --
Mauve with combination dark blue/white/red stripe, rounded French cuffs, glorious pattern matching, excellent spread collar, two-fold 100s cotton of the highest quality.
My first Charvet bespoke:
rounded 2-button cuffs, spread collar, blue-green fine twill from their "Opera" (don't ask me, I wouldn't wear a shirt this color to the opera) cloth collection.
If I had my Carlo Franco shirt maybe it would take pride of place here. Hopefully Chuck ships to Freedom.
