DAVID.ANNMen's Slim Fit Casual One Button Blazer Jacket

Como me puedo contactar con el probeedor de este articulo?

are the pockets real? or it's just cut marks?

I fit a medium t shirt well and a large is a little bigger but I’m 5’ 6” with broader shoulders, should I up it to a large for the blazer?

I am 5’7 and 220 lbs what size would fit me
