"This shirt is amazing! I love everything about it! Both the fabric and the length of the shirt make for super comfort! I love that the shirt doesn’t fall on or below my bum and rather it sits right above (perfect for high waisted leggings or shorts). The sleeves are very flattering, fitted and fall right at about my upper bicep which for me is perfect! I immediately ordered in another color because I love it so much!"
"I wear leggings a lot for my workouts and I love how Definite Articles look and feel great, and I don't have to worry about chemicals. I will definitely be ordering more! I also bought some leggings for my teenage daughter and she loves them too!"
"So comfortable and perfect fit (I got a small and I’m 5’3”). Flattering without being too loose or tight. I love it"
"so I got this to be a workout shirt. I was looking for something that wasn’t leaching chemicals into my skin everytime I sweat. And I wanted a clean semi-fitted polished look for when I was teaching yoga and Pilates. And this tshirt is absolutely perfect for that. Fitted without being too tight, doesn’t ride or roll, and it’s so so so soft. But the kicker? It’s also just the perfect whenever tshirt. I’ve found myself absolutely living in it ok my day to day with jeans. Came back here to buy a few more and felt I needed to buy share this review. Thanks for making the perfect black tee!"
"Soft feel and a great fit."
"Soft, lightweight and perfect sun coverage of chest and shoulders while outside. Hiked all day and couldn't be happier with this shirt. It's a bit long, which is nice for hiking because it covers the backpack during hiking. However for a class workout, I am buying another so I can cut/crop it. :) I am 5'2" | 114lbs | Wearing Size Small (I like some room while moving)"
"The fabric is like butter and supportive"
"I love this tee! The perfect complement to my DA workout gear, fits great and provides coverage when I need it. thank you for a great fitting Tee!"
"Love the new T from Definite Articles. Fits perfectly and by far the most comfy leisure shirt I have. Can wear it anywhere and for any activity. Plus, completely non-toxic!"
"Love my DA tees! Perfect fit, comfortable, and perfect for working out or summer fun!"
