I personally didn't size up and took my normal size (48). The jacket does have the actual "bomber" feel so it's cropped and slightly oversized but I didn't experience it to be significant. It really just depends on your body type.
How are the suede chelsea boots/ zip boots supposed to fit? I'm 43.5 and got a pair in size 43. There is no way they could go off my feets but my heels feel "off" a bit with each step. Feel like could have been 0.5 smaller.
Sole length is ok but should they be really snug at the ankles?
