My first version had some fitting issues, especially a too wide band and wires poking in my underarm.
I found the grading of the pattern to be confusing, so I stuck with 34C and modified the pattern pieces. That was taking 2.5 cm out of each side seam, lowering the top by 0.5 cm under the arms and moving the straps inwards by 1.5 cm.
The high waist panties are selfdrafted, but for the lace overlay I oriented on Madalynne's 8228 pantie style lines. Looks very flattering and not that huge once they are on! ;)
