Let me just say, I hate CK's advertising, and I hate paying more than $20 for a frickin' t-shirt.

HOWEVER!  Since my first micro modal CK shirt purchase two years ago, it's ALL I WEAR, EVER (well, almost).  These shirts are insanely soft and comfortable, and I absolutely love the fit.  I am 6'2", slim, with a large bust, which is basically a model's build but SURPRISE!  No one sells stuff that actually fits models!  I guarantee what you see in the advertisements is tailored garments, because it is a rare occasion indeed when I find a shirt that even remotely fits me, especially length-wise.  But these shirts fit PERFECTLY and that is no exaggeration.  They also last through many washings without pilling (I wear them literally every day and they last for at least 6 months before the pilling starts, and even then it's mild) and without holes developing despite the thin fabric (I like thin fabric).  They also retain their color extremely well.

I cannot recommend these shirts highly enough to people with tall & slim builds, male or female.  A word of caution, though: the fabric is quite thin, almost sheer, and they are shaped to fit a slim build, so if you don't want bulges highlighted you probably want to wear these as an undershirt.

EDIT: You can get these shirts for <$20 on Ebay, and in a wider variety of colors, too.  I recently bought salmon, teal, navy blue, and maroon shirts from a seller in Israel and am very happy with that purchase.
