Client: Carl, a tall man who is having a hard time finding slim and modern fitting tall dress shirts that fit his neck and arms without being too baggy in the chest area.

Wants:  Dress Shirts in size Chest 40 – 42, Neck 17.5, Sleeve 36 / 37, Slim / Modern fit

Budget: Prefers under $50 but could go as high as $100.

One idea is to get a custom made dress shirt from Blank Label. Their custom shirts start at $85.
To get proper measurements, you can either visit a tailor, or you can lay down a shirt that fits you well on a flat surface and take your measurements. Then you can easily enter them on their website.

This blue stripe shirt is $90.

My son has a 16″ neck, but just this past weekend, we had to have a dress shirt for a band competition. We ended up having to get one with a 17.5″ neck to fit his 36″ arms.  Here is the shirt we purchased.  It has a bit of stretch and feels nice:
