My basic tees right now are Jcrew vintage (crew, scoop & v-neck) and the LOFT sun-washed V-neck. I have had both for a couple years now, no holes have developed and I just toss them in the wash and dryer with no special handling (except that the water is usually cold, not warm or hot, to save $). In fact, I just bought a few more of the Jcrew's.
I will say that the Jcrew fit has changed recently; the new ones are a bit less baggy than the older -- but still not too clingy or tight. Though I did need to play around with the sizing, i.e., I sized up. So the older ones are size XS, the newer ones are S, and yet the older XS's are actually looser in fit than the new Small's. Go figure.
Please note I am apple shape and my squishy jiggly belly always needs to be accommodated (hidden) with ANY top, so I am quite particular about fit around the mid-section, especially tee shirts.
I really like the Jcrew scoop neck. It is a flattering neckline, not too low, just right. I also was surprised to find I liked the crew neck, as typically I can't stand crew necks due to my short neck. But the ones I added had a lower cut than typical crew necks, so somehow, it works.
But in the end they are just tee shirts -- I would not think to wear any of these to work, even on a casual friday. For a more polished version that can be worn to work (or for smart casual), I recently added a Jcrew suiting tee. The material is more substantial, stretches, but please note, also clings more. I also found similar suiting tees at Talbot's recently, which I like a lot, which is even more substantial than the Jcrew version, except that they arrived with that weird odor that I'm hoping will go away.
