This is a great shirt. A size 10 fits my 10 year old perfectly... which is great for this band concert, but makes me wish I had sized up for some growing room! It's definitely a "modern" or slim fit. if your kid isn't very thin, I would size up. It is a very fitted, slim fit. It's a little thin fabric-wise, but that's kind of the dress shirt look. Definitely needs an undershirt.
For size reference - my son is 14, about 5'4 and 116 pounds. Bought the size 16 and it is perfect, maybe even a little room to grow. Nice, comfortable, thin shirt. Loved the price I got on Amazon ($15 less than department store), especially since it was for a special occasion and may not have the chance to wear it again before he outgrows it.
This shirt with a $30 price tag I paid $7 Dollars for! The price alone should give this 5 stars. The quality is good. The color is spot on and doesn't bleed. It looks expensive and is high quality. My son gets many compliments on this shirt. He is pretty much a size 4 I got a size 5 hoping it would last a while and it actually is a little short in the sleeves and just slightly in the body. He is tall and slim though. Also the fold creases are stubborn and will most likely need to be ironed. Those are the only two flaws I can find though.
Great price for a really nice shirt. My son is 13, 5'4 and 100 pounds with long arms. The 18 fit him perfectly. Plenty of arm length and not too big around like the adult sizes are. Perfect fit for a long and lean teen. I'd say it's lightweight, which is nice for comfort...but not thin and cheap.
I like the look and feel of this shirt, and the quality despite being designed for boys. I am 26, but have a small frame, so adult smalls are just too large, and the quality of boys shirts is often lower due to most people only wearing them for a short duration. I am very pleased that this is a quality shirt that fits better than an adult size would.
Great basic dress shirt. My son is a bit "thick" around the middle but this shirt fits him nicely. This is the second one we've purchased and have been very happy with the way it washes up, only needs light ironing and I've been able to get post-concert ice cream stains out of it easily!
