I am in the market for a new suit and maybe a separate sport coat to update my closet. I wear a suit maybe 3-4 times a year work and sport coat 6 times a year.. is there any reason to spend extra money on a suit or will most be similar in style and structure, just comfort?

I see some of the box stores have sales and can get these them for 2-300 for suit vs 5-600 in the Jo’s a banks and other more specialty stores
