The Mexx suit is sold pending payment.
The Chu jacket as it is made in Italy is sizewise similar to other italian and european makers, so It is a bit roomier than an US 38R, but not that much as you have seen on some PZ white labels I have sold.
I posted measurements. This particular Chu jacket has soft shoulders and unfinished sleeves, ticket pocket and an unusual linen fabric with contrasting light blue lining and undercollar that would look great on the spring/summer.
I have also a NWT PZ 100% linen jacket, half lined, 2 buttons, 2 vents on and "standard" lightweight cream fabric that would be the perfect jacket for the summer. in EUR 50 to be put for sale for around $270 , I'll post pictures and measurements later.
