Thanks for your quick reply, may I ask how old is this suit? The reason I'm asking is, it seems this suit is atleast 6-7 yrs old. The bezel of the sleeves buttons are much more thinner and flatter compared to the later ones. The Windsor back then tend to be more skinnier cut on the shoulders and armhole compared to now; I fit the current 48R base A with no arts required but the earlier collection I have it in a 52R! So this suit might actually fit me.
