The fabric is soft and the fit is comfortable, sized up two sizes based on reviews. I changed out the pads because they were almost too large and thin and wrinkled even after washing and hand shaping and laying out to dry.

I bought my first set from Aktiiv almost two years ago, and I absolutely love it. It’s still in excellent condition, even though I wear it at least once a week. Sometimes twice. (I always wash it on delicate and let it air dry)
That’s why I decided to get a second set. This time I chose the square neck to try something different. I have a size small in the racerback, and I initially ordered a small in the square neck too, but it felt a bit tight. The medium fits better, so I think I’m in between sizes. I agree with what others have said here. It’s better to size up for a more comfortable fit. It's very cute, I got a lot of compliments!
The quality of the pieces is excellent, and the customer service is great as well. I needed to make an exchange, and the process was super smooth.
Highly recommend!

Great to have a unique but classy sports bra style- ordered one and two sizes larger than the size chart after reading reviews and I ended up keeping the bra that is 2 sizes larger than what the chart says
