I'm the same size as you, lovelux, and size 42 should fit you. You can order size 42 here: http://www.heatherwallace.com/men_camelhair_detail.php?prod_ID=37
If you are after a slim/tight fit, then you need a smaller size.
I could move up a size sometimes, you know. I didn't do that for the LBM coat because its sleeves didn't allow much shortening. That safari jacket I'm looking at is small in the shoulders for me, too. Actually, a lot of the shirts, coats and jackets NMWA sells are small in the shoulders for me.
What I'm saying is, you never know when we're going after the same size.
I know the S/S 14 stock isn't ready yet, but kopping waits for no one. I've been looking for a (very) light summer jacket/shirt-jacket that's wearable even in hot, humid weather (30+ Celsius).
I'm eyeing this safari jacket right now.
1) Kop it.
2) Not kop it 'cause you've something much more awesome coming up.
3) Not kop it 'cause it's no good and I'm too stupid to tell.
4) Kop it and kop your awesome wares when they are ready.
Don't know how the Casentinos fit, but the hopsack coat is very slim. I usually wear 38S, and the hopsack in 48 fits me closely, with no room for a SC or a heavy knit.The coat has non-working cuffs, but made to look like they work. There are slits, which make me think you can't shorten the sleeves too much.It's a cut that favours the skinny and the long-armed. Chances are you'll have to size up.
If anyone's looking for Piccolo's shirts on Frans Boone, the web site actually has more listed under the 'Previous Season' sale section. Those shirts would not show up should you search by brand.
