I don't know what kind of experience they require from their alterations people, or how well they're trained. I would imagine that most of them know what they're doing, but again I have no experience with that company.
Wide straps would just be tacked into the interlining, though, whereas the cap sleeves in your other picture would involve a lot more handling and stitching into the bodice. Just food for thought, I guess.
