Bit of a weird phenomenon on my 3rd made-to-measure Samuelsohn suit under Canadian haberdasher Harry Rosen's JP Tilford imprint. The first two turned out great, and this one is also fantastic except for what you see in the pictures below: unsightly ripples along the shoulders. I tried to find out online what might be causing it, but couldn't come up with much. To make matters worse, the in-house tailor at Harry Rosen tried to fix it by "letting out" the shoulders, and it did nothing (the pics below are after this alteration). The salesman at Harry Rosen maintains it is not a fit issue and rather attributes the ripples to the fact that the suit is made from a finer fabric and with a smaller shoulder (I selected Samuelsohn's least structured fit), but I'm confident it has nothing to do with that, since I have plenty of jackets in lighter fabrics with less or no structure that do not have this issue.
I'm a bit peeved because my OTR suits and jackets from Suit Supply, Kent Wang, Brooks Brothers, LBM etc. do not have this issue, nor do the first two JP Tilford suits I bought. And at around $1400, I expect it to be more or less perfect. So, I turn to the wise persons of Styleforum to ask: what is causing this, can it be fixed, and to what degree should I put my foot down with Harry Rosen? Would I be justified asking them to remake it? Or am I being unreasonable and this just goes with the territory when it comes to MTM? Frankly if they don't resolve it I probably wouldn't buy another suit from them, which definitely isn't in their long-term interest since I'm a youngish guy with many suit purchases to look forward to. Appreciate your insights!
Apologies, it was kind of hard to get the pics just right, the issue looks more pronounced in real life (you'll notice the salesman chalked the ripples to bring to the tailor's attention for a second attempt at fixing them):
