It might be easier to find well fitting t-shirts, but these t-shirts may be A) too expensive due to a 'better' cut B) only available online due to the niche brand or C) still not the perfect fit for you because you have a particular body. And even if your ideal t-shirts are available out there, whats to say they aren't the style you like? Say you prefer printed designer t-shirts that don't come in so many varieties as a white t-shirt does, do you forfeit your style because of a silly rule that t-shirts are 'just t-shirts' and shouldn't be altered? It's a pointless limitation that has no merit, alter your t-shirts if you need to, just like any other garment you wear.
