A slogan t-shirt works when the joke lands. These are the ones where the humour is actually funny rather than trying too hard, which matters when you are dressing a son who will definitely call you out if it is not. The slogans range from silly to clever and they are printed on decent quality cotton that will survive actual wearing and washing. Fit ranges from fitted to oversized depending on preference. These are the t-shirts that make him laugh rather than cringe, which is genuinely the benchmark that matters.
