Same. I have a workout shirt from when I was 15 (I'm in my 30s now) that has seen literally hundreds, even a thousand+ workouts.

However the cotton fabric used in most off the shelf clothing is also not what it used to be. My dad, who doesn't like to throw things away, still has his old clothes from when he was in his 30s (he is in his late 70s now). They've retained their shape far better than my 3 year old clothes.

Most modern clothes take all the possible shortcuts from material to assembly they possibly can to deliver a $30 sweater that holds up until you pay at the checkout. If you want a long lasting one, they’re available from specialty manufacturers but the price will be over $200

Manufacturers that cater to EMS and Military produce some very durable clothes. Propper's emt pants are currently my go-to.

Work clothes in general tend to be higher quality and last much longer than fast fashion. A pair of chinos or cotton twill pants from a respected workwear manufacturer is what I would recommend for daily wear.

Or you buy a nice vintage item, used. They are better made and more affordable.
