A pretty simple question: what's everything you want in the ideal dress shirt? The answer (I hope) is: slim fit, non-iron, monogram-able, unbreakable buttons, an unlimited return policy, and about $35 or less.
Now who can offer all that? Brooks Brothers and Charles Tyrwhitt offer great shirts, but you pay a premium just for the brand. Lands End's Dress Shirts, on the other hand, hit all of these marks at the right price.
Even better: for Father's Day, LE is offering $20 off of $75 plus free shipping no minimum with code FATHER and pin 2610.
