A wood-brown winter suit for formal occasions

#WearItWednesdays

The model wears a three-piece single-breasted suit made of 100% wool. The wood brown does wonders for formality and elegance. Moreover, the gray plaid checks make it a classic formal suit with a modern and traditional tapestry touch. The light blue solid buttoned-down shirt contrasts the brown suit and the candy-red necktie. A pocket square in the same red completes this layered winter formal look. 

Can you suggest the best shades of shoes for this ensemble?
