Yup, everything is pretty normal sized across the board for me.
I also agree with Mimo, though again, it depends on the fabric. The flannel (navy suit) and the wool-cashmere blend (tobacco jacket) will probably last a while. The other two I am less sure about (particularly the linen-wool blue peak lapel jacket). Maybe another 2-3 seasons with regular wear. Dunno. It's worth noting that both are spring pieces...I suspect their winter stuff is of sturdier fare.
