It was some time ago when I ordered a jersey from Rapha. (I purchased this jersey myself – they didn’t supply it).
I was very excited to get this jersey. First because it’s black. Other than my IDC/Wheeler jersey, I wear jerseys that are a majority black. I have a 34D(DD) chest and larger arms. I personally didn’t mind the ‘girls’ being highlighted by the medium I originally ordered, but the arms were way too snug to deal with for 100 miles.
I went on to get a replacement in a large, which fit perfectly (except for the bump at my middle, right where I don’t want it).
