Why Do T-Shirts Lose Their Shape?
Recovery
Your T-shirts lose their shape because the knit has nothing in it to pull back, and because heat takes out whatever pull-back it had. A cotton blend with spandex in the yarn, washed cold and dried low, still fits a year in.
The shirt that goes slack first is rarely the cheapest in the drawer. It is the one worn Saturday, thrown into a hot load Sunday and left in the dryer until bone dry. Two of those are habits. The third is something you bought.
Why Do T-Shirts Lose Their Shape?
A jersey knit is a grid of loops. Wearing it pulls the loops open, and the only thing that closes them again is a fibre with recovery in it. Cotton on its own has almost none.
Pull a sleeve and let go. A shirt with recovery snaps back. A shirt without it stays where you left it, a little wider every time. That is the whole mechanism.
Heat makes it worse. Spandex behaves like fine rubber, and rubber that gets hot and then gets pulled goes slack. A hot wash softens it, a hot dryer finishes the job, and the shirt comes out looser than it went in. Nothing about the fit was wrong. The yarn stopped doing its job.
What Gives a Knit Its Recovery?
Stretch fibre and low heat, in that order. Spandex is what pulls a knit back, and keeping it away from high heat is what keeps the spandex working.
Every tee PILLAR makes has spandex in the yarn. The Nick and the Joey run 60% cotton, 35% rayon and 5% spandex. The Tim runs 88% polyester and 12% spandex, the most stretch fibre in the line. What four way stretch actually does covers the difference between a fabric that gives one way and one that gives every way.
The fibre only does half the work.

The First Place a Tee Goes Slack
The neck opening, then the shoulder line, then the hem. Each one takes a different kind of handling, which is why they give out in that order.
The neck goes first because you stretch it over your head twice a day and because a hanger hooks it open while the shirt rests. A collar that has already gone wide can be worked on. The shoulders go next, since that is where the shirt's weight hangs, and a wet shirt on a hanger weighs a good deal more than a dry one. The hem goes last, and usually because of your waistband rather than the wash.
Every tee in your drawer is either pulling itself back into shape or it is not, and that was decided the day you bought it.

Is a Shapeless Tee Worth Keeping?
If the shoulder seams have slid down your arms, no. A wide neck can be worked on and a loose body can be lived with, but a dropped shoulder line is not coming back.
The shoulder is the one measurement a tee cannot fake. Once that seam has moved, the shirt reads wrong under a layer and worse on its own. That one goes in the gym pile. Knowing when a piece is finished is the same call, wider.
Everything else is salvageable enough to be worth changing the laundry for. Cold water, a short spin, out of the dryer slightly damp, folded rather than hung. Do that with the next shirt you buy and you will learn how much of this was ever the shirt.

Frequently Asked Questions
Why does my T-shirt look baggy after one wash?
Almost always heat. A hot wash and a hot dryer relax the stretch fibre in a knit, so the shirt comes out wider rather than tighter. Wash the next one cold and take it out of the dryer slightly damp, while it still has some give.
Does the dryer make T-shirts lose their shape?
High heat does. The tumbling is not the problem, the temperature is. Spandex is the fibre that pulls a knit back into shape, and heat takes that pull out of it. A low setting keeps the fit you paid for.
Can a T-shirt that has gone shapeless be saved?
Partly. A wide neck responds to steam and a cold wash, and a loose body reads better folded flat than hung. What cannot be fixed is a shoulder seam that has slid down your arm, because that is the shirt's frame rather than its fabric.
How long should a T-shirt keep its shape?
There is no fixed number, and any brand quoting one is guessing. What decides it is whether the yarn has recovery and whether the shirt sees high heat. A blend with spandex, washed cold and dried low, holds its line long after a plain cotton tee has gone wide at the neck.
