Since you're the johnny-on-the-spot, any recs for tanks? Can't quite bring myself to pull the trigger on JE (that thread is a bunch of dudes saying every item is "fire"), but I know you've usually got a good eye on who's offering good stuff.
As an experiment, Fok should merge Alden, John Elliot, and MC WAYWT threads to see what happens.
The ones I probably wear most often are:
voidthebrand straight-hem tank: http://www.voidthebrand.com/collections/all/products/straight-hem-tank. TTS isn't tight in the chest, but it'll still stack / bunch around the waist. It has unfinished hems and the collar doesn't like entirely flat, which looks kind of intentionally sloppy and some people probably hate. 50 modal / 50 cotton, which feels really nice (same fabric mix as JE+Co). White is kind of transparent, so probably best for layering unless you're into showing the world your nipples.
Geller 2nds split hem tank: I haven't seen any since S/S '14, but they were really long and soft 100% cotton. I had to size up two (from M to XL) to get a normal fit. Not sure if or when these'll come back.
UO BDG tri-blend slub tank: Also from last S/S. Nice and long with a curved hem. Terrible quality (you gotta check to see if it's stitched properly before buying it / deciding to keep it), but kind of a cool fabric. Gotta size up one.
COS silk blend pocket tank: Kinda thin and fragile, but lightweight and really airy. I got a couple on sale when everything was ridiculously cheap.
Of course, three out of four aren't available, and I wouldn't be surprised if the vtb stock was kind of depleted at this point.
