Frustrated by the sizing. Having carefully measured my chest, as described in the sizing guide, I picked the product size (48) closest to my measurements (47). When it arrived the garment was HUGE!! I rang customer services twice to ask how I should have done it and it was clear the first chap I spoke to didn’t have a clue what I was talking about. The second time, the chap confirmed I had correctly selected the product size 48 (although, why a size 48 should actually be over 50” on the garment is beyond me). Clearly the instructions are incorrect and the correct size is the one where the actual garment size matches the body measurement.
