I get your point about fit, but have a comment or two about fabric.Warning: Spoiler! (Click to show)
The t-shirts don't feel that soft out of the box. I think Nan said something about the processes used just before packing the t-shirts affecting their handfeel on arrival. After you wash them they get much softer. I didn't believe what someone else on the forum said about that until I did it for myself, and it's been true of each of my t-shirts from them. In my experience (and from what I was told a few years back as a sales associate at J Crew), much of the softness of items from BR and J Crew is from the heavy-duty fabric softeners they use before the products go to stores. The downside is often that those wash out over time, and the items become less soft. So far in my experience, the softness of the Everlane tees seems to be a quality of the fabric, not of a chemical. If anything, it seems you need to wash out a chemical at the beginning.
When it comes to the weight of the fabric, I tend to think that different weights are good for different things. Everlane tees are great for hot summers, and now that it's cooler I'm layering them under button-ups or sweaters. I also have other brands of t-shirts of other weights that I use in different ways, but most of them are not as soft (after the wash). Then too, BR t-shirts have been too short for me in the past.
Just thought I'd add my two cents to yours. Hope it helps.
Hey thanks for your comments! I always did suspect that J.Crew and BR used chemicals to make their shirts unrealy soft, but I do appreciate the shorter fit of the BR shirts. To each his own I guess!
