Trying to buy dress shirts on a budget (preferably $40-60 per shirt). I'm a fairly slim guy and I have problems finding shirts that don't bag out in the back. I've seen brooks brothers, CT shirts, modern tailor, land's end. I'm running into paralysis by analysis. I don't need super high quality because I wear dress shirts pretty rarely (only to important meetings and such at work). But I would like to avoid looking like a dork who only buys van heusen shirts. What would styleforum guys recommend as far as what brands and styles I should buy?
