    Loose under arms, flattens you out
    Special Size: with Contrast Trim, Size: Medium, Color: Black/White
    I saw an influencer recommend this workout top, but was disappointed in the look and fit. It was saggy under the arms and flattened by bust in an unflattering way. This was returned.

    Definitely an essential jacket for athletic-wear & flattering
    Special Size Type: Full Zip, Size: XX-Large, Color: Black
    Great quality for a great price! I was looking for a versatile athletic jacket to run in that fits over light tops & found this on Amazon. There were only a few left so I grabbed it right away, so glad I did! It's warm enough for early fall, I live in NC so I will probably use it throughout the winter too bc it's warm here. I feel like the arm length is a bit long & the sleeves a little bit tight under LS Tops but are meant to be. This is a form-fitting jacket, it does run small. I usually have to size down from an XXL to an XL in Amazon Essentials clothing bc they run big but this jacket fits me in my regular size XXL. I tried to find this type of jacket at a few different places & already out of stock in October! If it's available, buy it! You'll love it! I hope more colors are available in the future!

    Nice looking and soft
    Special Size Type: Full Zip, Size: XX-Large, Color: Slate Grey
    Soft fabric and great color (grayish purplish/bluish). Pants fit nicely, but I may have been able to size down just for how high I can pull them up and them slipping down. On the other hand, I wish the jacket was bigger. It fits probably like it’s supposed to but you can definitely see every lump on my stomach. I will wear it unzipped. The material is medium weight, very stretchy, and nice. I do think it will probably pill- it just seems like things I’ve had that do. I won’t dry it. I’m 5’4” and weigh 195.
