What you are paying for in a t-shirt
Most t-shirts fail in the same three places, and none of them is the fabric on day one.
The first is knit density. A heavier jersey has more yarn per inch, which is what stops the fabric from going translucent at the shoulder. The second is the neckband. A ribbed collar with enough elastic recovery returns to its shape every time you pull the shirt over your head; a thin one gives up in a season and never comes back. The third is where the seams sit. The Drew Long Sleeve runs a seam down the center back, which is a construction decision you can see. Look closely: our newest essential tees are finished with AMO’s signature burgundy thread at the back of the neck and waist.
Vintage jersey is a hand rather than a look. The Forever Tee uses one: a yarn spun with enough irregularity that the surface has texture, so the fabric drapes closer to the body than a smooth modern knit. The Lovey Tee runs the other way, a plain cotton crew built to be a base layer.
The fits, from shrunken to oversized
Four fits run through the grid and they land in different places on the body.
The Jade Tee is shrunken, cut short in the body in a baby rib that follows the shape underneath it. The Lovey Tee is a relaxed crew, straight through the body with room at the arm. The Cherie Tee is properly oversized, wide at the shoulder and long enough to wear untucked over anything. The Forever Tee is a slimmer cut, with a curved hem. The Rumi Tee sits between the first two, a ribbed scoop with a clean back seam.
Which one you want depends on the waistband it is going over. A shrunken tee ends at or just above a high waistband on its own, so the rise stays visible without any effort. An oversized crew covers the waistband completely unless you tuck the front, and a front tuck is what turns Cherie from a shirt into a proportion. This is the argument for owning both, and it's why a denim brand sells t-shirts at all. Everything in women's jeans assumes something is happening above the waistband.
The white t-shirt
A white t-shirt shows everything. A shoulder seam sitting slightly off is invisible in black and obvious in white, which is why white is the honest way to judge how a shirt is made. Opacity matters here in the same way it does in white denim, and it comes down to how densely the jersey is knitted.
The other thing to know about white is that it moves. Cotton yellows at the collar over time and grays if you wash it with color. A white tee wears out faster than a black one, and a better one buys you more wears before that happens.
White runs through five styles here: the Jade Tee, the Lovey Tee, the Cherie Tee, the Quinn Long Sleeve and the Jade Long Sleeve. The grid also carries Eggshell, Bone, and Natural Haze, which are off-whites with warmth rather than true whites. If you are matching a tee to white denim, that distinction matters.
The black t-shirt
Black asks the opposite of a jersey. Where white exposes construction, black hides it and shows wear instead: a black tee goes gray at the shoulders and along the folds long before it loses its shape, and how fast depends entirely on how deeply the yarn was dyed.
The blacks in this grid are deliberately different from each other. The Jade Tee, the Lovey Tee, the Reese Tee and the Jade Long Sleeve run a true black. The Lovey Long Sleeve is Vintage Black, dyed to look like it has already been washed a hundred times, and the Joanna Long Sleeve is Natural Black, a softer and slightly warmer version of the same idea. Any of them goes under high rise jeans without competing with the denim.
Long sleeve tees
The Quinn Long Sleeve is the lightest, cut in a barely-there jersey that goes under a knit or jacket without adding bulk at the arm. The Drew Long Sleeve is heavier and has a center-back seam. The Jade Long Sleeve exists because the Jade Tee sold, and it is the same shrunken baby rib with sleeves. The Lovey Long Sleeve is the relaxed crew in a longer sleeve. The Joanna Long Sleeve is a different garment: a ballet neckline with ribbing and a shaped body, closer to a top than to a t-shirt.
All are gathered at long sleeve tees.
Necklines, and what each one sits under
The neckline decides what the shirt can go under. A crew, like the Lovey Tee, closes the space at the collarbone and works under a crewneck knit or a jacket without either one showing. A scoop, like the Rumi Tee, opens that space, keeping a heavy layer from crowding the throat and giving a necklace somewhere to sit.
The Joanna Long Sleeve uses a ballet neckline, wide and shallow, which follows the line of the shoulder and takes a cardigan more gracefully than a crew does. The Reese Tee is a ribbed turtleneck, so it layers under everything and finishes an outfit on its own.
For the sleeveless version of the same logic, look at tank tops, and the rest of the women's tops sit alongside these.
