Nordstrom trim fit. Thank me later.
Can be had for $20 at the rack. I stock up on 5-6 fresh ones every year and rock em n then throw em out.
Only draw back is that there is only one collar shape, can't wear cufflinks, less choices
But if u wanna invest real dough go mtm like Pinoy and Wj4 said
20 though? At the rack?? I have a nordstrom rack right near work, Ima go tomorrow at lunch
Edit:
Sorry Just a quick question for all my db friends:
For the suit I'm wearing, what shirt would look best? I'm thinking white with a solid navy tie and maybe a white pocket square is my best bet.
For reference:

These shoes

Thank you kind gentleman who help.
