Where to Get Dress Shirts?

Where do the more heavily muscled members get dress shirts? I have a 19" neck and a 35" waist and cant find shirts anywhere that come close to fitting.

Go to Proper cloth (propercloth.com) and they will make shirts based on your size. You pick the fabric, style, etc… and give them your measurements (neck, chest, waist, etc…) on the website.

In the UK Sainsburys 18 1/2 , 19 collars under £15.

Men’s Wearhouse has some athletic fit dress shirts that are pretty nice. Dont have to custom order like the website mentioned above
