The Boden scoop tee I had was great.

I have 2 T shirts from 3 Dots that are several years old (at least 6) and are still going strong. They are on the short side but I love them. I bought 2 J Crew Ts last year and have been unimpressed with them. Great colours though.
I bought a very expensive T from Sarah Pacini last year that has been great. Lovely drape, washes well, perfect colours, nice scoop, kinda sexy. I think I will buy another one this year.

I don't wear tees very often except in summer, but I have that Vince tee that Jeneva mentions and it was such a great purchase. I got mine on sale, one in white and one in navy. At first I doubted my sanity (I am paying what for a t-shirt???), but it turns out these are fabulous as a winter layering piece that can also stand alone because of the interesting dropped shoulder and envelope neckline. The white one works with almost anything. And I can make the navy one into a faux dress with a navy skirt or a "jumpsuit" with navy crepe jogger pants. I do find the modal fabric is on the warm side, so for me these are fall/ winter/ early spring items only.

I also have the same linen boatneck tees that Bonnie G. mentions. Those are great but quite sheer so you may need a cami or tank, especially with light colours like white. Having said that, they're amazing layering pieces. The linen has lovely drape.

I can't believe it but I have had EXACTLY the same issues with my Everlane U neck tees as Jenava. Stains don't come out, and small holes develop from semi-tucking.

The best made cheap tees I have purchased have come from Uniqlo, Gap, H&M and Urban Outfitters (the $25 range ones). Zara tees are the worst in my experience. Lose their shape, seams twist, and stains don't come out. For some reason, the better the fabric, the easier it is to remove stains.

My Madewell tees are so-so, as are J Crew.

Otherwise I have purchased really nice tees that hold up well from Three Dots and Velvet. Splendid are OK, but quality is not so different from Gap and cost more.

I like the Gap tees, and the Merona Ultimate ones from Target. I like the fitted tees from Old Navy.

For those that wear the vince Tshirts, can you wear white with just a bra? Is it really sheer, or pretty good in that area?

for those will to spend a little more, I will also recommend this brand, Boxie, made in US, nice weight.

I buy a lot of men's tees (mostly with prints on at concerts) and it's true that the quality is far superior to their counterparts in womenswear. I wear them a bit loose with the sleeves cuffed and they work just fine.

Why not try a few shirts from the men's department? Cut and fit varies, so you may find a shape that works for you.

For those recommending Uniqlo, is the size chart accurate? I'm looking at a solid XL based on their measurements, but I'm more often in a medium or large at other retailers.

I have a white Vince boat neck tee, and yes, you can wear it alone. It is substantial enough that your bra doesn't show through. I wear mine under all my boat neck sweaters, but it could easily stand alone.
