Great shirt for working out
I wear this shirt for cardio and strength training almost every day and while it definitely fits small/tight, it has great stretch and is so so buttery soft. I agree with some of the other reviews and wish they offered it in a longer version because I always seem to be pulling it down because it leaves like 2 cm of skin showing between the hem and the top of my leggings. Either commit to being fully cropped, or be mid-length. I will however, be purchasing this is more colours and the long-sleeve version when it becomes available again.

Waste of money, my mom will never forgive me and neither will my armpits
While the shirt may be cute and comfortable, the thought that came to mind after wearing this it for a few hours was ,”sweat wicking my ass!” Ok I sweat, but I don’t need a supposed to be workout shirt highlighting that. This made me irreversibly insecure and it’s not like i have some sweating disorder. Screw this top and all that made it. 50 DAMN DOLLARS WHO IS GONNA EXPLAIN THAT TO MY MOM!

Really nice the best thing i ever bought
I bought a small im 5"2 and 127lbs and for anyone who wonders how to wash it personally to be on the safe side i clean it with a no rinse detergent but it on spin in the machine to get the water out and dry it. Since its 50$ a shirt i feel like its the easy way to keep it longer and for it to stay pretty and the shirt itself is really nice it hugs your body i wear it without a bra and you cant see anything (34D) its so comfortable the best thing ever.

How Does it Fit?
What Size Did You Order?
Pleasantly Surprised
150lb, rectangle body shape - I haven't been impressed by all of Aritzia's quality, but this shirt is good! Very soft, stretchy, seams aren't puckered. Thought it would be more of a spandex-type material, but it looks more cottony. Bought it for working out, but its actually a great every day shirt.

Great shirts
Great workout shirt, super comfortable. It's not a really breathable fabric so I do find I smell worse when I work out in it, but I like them to just wear around the house. All of the lighter colours are slightly see through

Highly Recommend
If I could give 4.5 stars I would. It’s so comfortable and I love the colour, it goes with everything. Love it. Also, personally I prefer the sports material over cotton so this is perfect

No support:(
I’m giving this 3 starts cause it’s super cute, but i was quite disappointed that this shirt didn’t come with a built in bra like the other TNActive tops.
