I ordered size 18-20 for 14 years. He usually wears size 16 shirts. These fit more like a 10-12. The sleeves ended just below the elbows.

LOVE these tagless long sleeve t-shirts for my little guy! This is our second purchase (in the next size up) because he loved the last ones so much; They have served us well for 2 seasons and can still pass in good condition. These shirts are very soft (like Gap quality!). The material holds up really well after washing and tumble drying (ours has been worn maybe 30 times) and doesn't shrink or stretch. It's medium weight and ideal for school, under sweatshirts, zip sweaters and flannel…

These t-shirts are very soft. Not too thin and not too bulky. My toddler can wear it alone or in layers on cold days. Good stretch keeps its shape. The perfect long sleeve shirt!

The best quality I've ever seen. It's not see-through, so it can be worn alone or as a tank top. Helps with warm mess. Washes well overtime. I had these for my daughter for a few years and bought her a size up. These average boys are BIGGER than tall girls. My son (almost 7 years old) doesn't want to wear them but he is 7/8. So if I bought a 5/6 it wouldn't be its actual size. In any case, in my opinion, they are large, which is better than small ones. I am keeping them because he will most…

The material is excellent, the label is seamless, fits my son perfectly, he is 6 years old and I have 5-6 in long sleeves. It's narrow and long but fits perfectly.! I would definitely recommend and will be buying more items in the future

I love these shirts! I love the colors, the fit and the softness. These shirts sit perfectly on the body. My grandson looks very handsome in his shirt.

To be honest I will never know exactly how this product wears and fits. I bought this set to make an angel Christmas tree wish for a 10 year old 12 year old boy who wanted a new outfit. I love that I was able to buy him 4 shirts and I pray they are comfortable and make him feel special.

The shirts are very soft and stretchy. The handles are elastic to keep them in place on your child's hands. Will definitely buy more.

To update. The seller contacted me and sent me new shirts that fit my son. I donated the rest for the cloakroom at my child's school. Excellent seller! Great customer service I ordered 11-13 year olds and these shirts are larger for 7-8 year olds. You are very small. And my son is not big for an 11 year old.

We've worn them solo and under shirts for every extra layer, and they work well with both. My first experience with Brix was their tank tops and the same deal I wore solo and under a sweatshirt in the summer when it got cold. I love that they have no tags and the material is stretchy and very soft for my boy's sensitive skin. The size is also included. They seem to be a bit longer than regular shirts and it also suits my boy's long torso well. I would recommend - and it's rare.

These shirts go great with short sleeves in the Florida winter! However, I will continue to buy, buy an extra size or two. For clarity, the picture shows a white shirt after a wash, the gray shirt has not yet been washed.

The pajamas are uncomfortable for my son. Instead, he goes to bed in a long-sleeved bix shirt. Just the right amount of warmth and breathability. He also wears them outside. On normal days I wear Brix shirts with jackets. The best comfortable shirts.

I really like that these shirts are 100% cotton and sold by a small business. Unfortunately, two out of four have shrunk even after washing in cold water and drying at low temperatures. I recommend buying one size larger. I bought size 14-16.

They are perfect for growing boys. The quality is excellent. They are very stretchy and very comfortable. I suggest trying on low heat so they don't shrink, but other than that my boys love them.

I bought these shirts to iron on stickers. The fabric was too stretchy and ripped. The cut was also very long and skinny. Not what I was looking for.

It fit my very tall 4 1/2 year old son well in a size 5/6. The cotton is thin, soft and great for layering a shirt or on its own. The torso was long enough for my nearly 4 inch baby. I will probably buy other colors.

I bought these for my 10 year old son who can be a bit picky about the softness of the fabric (spoiled kid haha... these shirts are good quality and very soft.

My son is 8 years old, average height boy. Size 9-10 shirts are very tight, especially around the shoulders and arms. Awkward and uncharacteristic for an 8 year old boy, but perhaps worn as a tank top or around the house. The quality of the cotton fabric seems to be good.

My 7 year old is slim so these stretchy fitted shirts fit well. They can be worn under a t-shirt or with pajama bottoms in cool weather. The price is great for the product 👍🏻

My son decided he just needed cotton pajamas. These are harder to find than you can imagine for an almost 11 year old. So I found good cotton pajama bottoms and then these shirts were PERFECT. They are a bit tight so one size larger than usual is a good choice. They make a great winter shirt when paired with a great flannel and then over a jacket. They are so comfortable and soft my son wants to wear them all the time but I told him they are like pajamas. Thank you for offering a great product!
