17.2 inch suit jacket shoulders for ~16.75 inch natural shoulders?

[LittleWing]

Hello, all. I'm currently looking at a used SuitSupply suit on eBay, size 34R. I believe everything about the suit would fit me according to my natural measurements except for the shoulders. As stated in the title, my natural shoulders are a bit on the small side and so I'm worried this suit won't fit. I also don't really have any suit jackets or blazers that I can use to compare sizing. Would this size work for my measurements, or should I look for a 32R instead?
