Good question. I think that it depends on what looks you’re going for. If you want a more streetwear vibe, go for a size bigger than what you’re usually buy. But if you want a more fitted look, just wear your t-shirt and notice the Ncis 20 years of 2003 2023 thank you for the memories signature shirt moreover I will buy this shoulder part, if the line between the shoulder and the sleeve is perfectly nsync with where your shoulder ends, it’s the one for you. All t-shirts are different tho, Zara tees are different than H&M’s and the list goes on. Just try the shirt on, if you feel comfortable and you think it looks good, then it’s for you. A t-shirt that’s too tight will make you look awkward also so becareful to choose a one that is not too short (overall length and sleeves). Hope this helps
