I have a t-shirt I bought at the Gap around 1996 that is still wearable, though a bit worn-looking where the collar meets the shoulder seams. Thick, sturdy cotton. It was probably around $15, which would be about $30 today.

There is no such plain ladies’ fit t-shirt consistently offered anymore. Either tissue-thin and less than $20, or involves a silly print and/or ruffles and lace.
