Well fitting tees are one of the hardest to find imo. With so much variation in sizes among brands and body shapes, what may fit well for one person may not fit well for another.
For basics, I love Zara's superslim range. I'm an Asian dude who works out a moderate amount and have a slight V-shape to my upper body with pretty well developed chest and arms. A lot of problems I face when buying tees are that if the chest and arms fit snugly (which is my preference), my waist area tends to have a lot of excess cloth billowing out at the sides, which is not a good look. Basically, I'm a M on my upper half of my torso and a S and my lower half. Zara's superslim range is great in that it fits well albeit abit too lengthy, which is easily fixed at a tailor.
I've tried Abercrombie's basic muscle tees and I have no idea why their sleeves look incredible short on my arms, almost like ladies' cap sleeves.
Anyone has any labels to recommend? I'm based in Singapore so preferably labels that has a presence here or ships here. Many thanks!
