white out

i've recently accepted that my style is relatively casual (but not cheap) and sporty. my eye naturally went for for t-shirts and jeans while i was doing some online window shopping the other day. however, when i do look for more dressy and mature clothing, i am very selective. i am in dire need of a white oxford. i rearranged my closet a few weeks ago to find that i am without one. i was surprised to find the absence of such a staple in what every man should have in his wardrobe. now that i'm looking for one, let's lay out some guidelines: i want something relatively tailored, but not too loose with a button-down collar (so functional) and a pocket (i just like 'em). i'm moving into the job market but i still want to be comfortable and youthful.

barneys lead me to this beautiful helmut lang shirt:
but the steep $275 price tag had me searching in another direction. if only, right?

however, i think i have found what i am looking for in this fink oxford from urban outfitters. it's currently on sale for $12.99 and it seems to have all of the qualities i want from a white shirt.

is this one of those things where you should buy it in multiples like black pants or grey t-shirts?
