Where is the famous place for shoulder filler design to achieve square shoulders?

I've been worrying about my shoulder line being too round, so I'm planning to go for a consultation.

I want a shoulder filler design that drops sharply at a right angle, but I'm worried it might look strange if it's too excessive haha.

I don't have trapezius muscles, but for some reason, my clothes just don't fit well, which is actually kind of stressful haha.

Which clinic would be good where the director personally and meticulously oversees the shoulder filler design?

I don't want a factory-style place; I want to go somewhere that carefully adjusts the procedure to fit my body type.

I'm looking at a few famous places, but it's really hard to decide.

I'm curious if there are any clinics with a director who has a great sense of design.
