I have washed it about 5-6 times and I can't say that I see any knots as mentioned. The fabric is thin and flexible. The size is more or less true to size. If you are usually in between sizes like M/L, then go for M if you want a tighter fit, L if you want a looser fit.

At first, it seemed very good in terms of quality. However, after 2 washes, the fabric has started to form knots in areas of body friction, such as the armpits and the side waist. I have never experienced this with a branded t-shirt before

The shirt has knots and the color has faded. I wouldn't say it's comfortable either because with the print on the chest, you sweat easily. I suggest avoiding it
