"Love this workout top and the fact I don’t need to worry about microplastics or weird chemicals! Super comfy material. Great for working out or just lounging. It does run small though - I am normally a large, sometimes XL. Ordered an XL and it’s pretty snug! Still cute and comfy though. But definitely size up 1-2 sizes if you want it looser."
"Had to go back and order a second one in a different color. Love the fit, super cute look, feels great."
"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!"
"Love the Tee, very light, comfortable and healthy!"
"Soft. flattering. Great for workouts or a night out. And toxin free! Buying more for sure!"
"This shirt is not to thick and it's great for the gym because it is airy and light yet substantial."
"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."
