Everyone says get the biggest offered, I’m the same as you except a bit taller, I got 345 and at first thought oh no too big, now I think they be just right, I should come out at a d. Think it also depends if under or over too as under makes them appear smaller x I know it’s so confusing as everyone gets different results! Just go with your gut x (and the biggest size they offer as they know what will fit your body :0)
