I am a bit confused by your sizing charts – Is the measurement given in the sizing chart a B cup or the upper bust measurement ? I realise the finished garment measurements for cup sizes are included but these all contain ease and I want to check that the finished garment will fit me across the shoulders. My upper bust is 35 inches and my full bust is 38 – ie a c cup. I am looking at the classic shirt – thank you 🙏

Hi Figen, as one without much “up front” my experience with bust measurements is limited, but:
I believe the bust measurements as per the chart will be the B cup.
A nice shirt fit is often all about the shoulders, so I’d suggest choosing your size based on your upper bust measurement and then using the C cup pattern tissue which saves you having to do an FBA.

I wrote a whole blog post to explain. I hope this helps!
