A basic white t-shirt is the simplest and most classically stylish choice. Patterned shirts can get a little too busy and scream out that you’re trying too hard.
If you’re going to attempt the t-shirt with a suit look, always go with a v-neck. This look is all about being casual and a crew neck t-shirt will appear a little too “buttoned up.” Give your v-neck a gentle tug to loosen it up a little more for an edgier feel.
To tuck or not to tuck? Personally, I like to tuck. I’ve tried it untucked before, but I always feel it looks too sloppy and feels indecisive.
