Experimentation. I think it's a good antidote to the excessive seriousness that occasionally undermines the bespoke journey. To that end, I recently picked up a Western-style shirt from Freddy Vandecasteele. It's similar to the one Freddy is wearing but lacks the two-tone treatment, features a modified scalloping of the front yoke, has different pockets and is made up of a slightly darker pink end-on-end cotton.
I worked with Freddy to modify the front scalloping and the pocket design. The edging of the yokes are attached using an overlapping seam.
I think the shirt goes well with denim (I wear it with a pair of darker rinse Seven For All Mankind jeans) and probably appealing to the younger guy - or perhaps I'm just flattering myself! Anyway, I won't experiment so far as to leave this or my other shirts untucked but Freddy will shorten the shirt length if that is your style.
I'm still on the hook for the finishing entries of my recent trip to Europe: Florence, Rome and Naples. I hope to write these up in the next few weeks.
