"Ordered this gorgeous jacket mainly for the colour and as soon as I slipped it on and zipped it up I had to go order it in black!! I love the way it hugs my body and makes me feel snug and compliments my shape so nicely ! I’ve brought a medium and it is a little ‘tight’ but I do prefer a nice snug fit."
"This jacket makes you feel so fit! Fits so well and material is so stretchy. Mine did come with a few stains on the sleeves but the customer support was fantastic and helped right away!"
"Love the fit and feel. I took the advice of others and sized up. This worked out well as it's still fitted and does up without being too tight. The fabric is great. Can wear with all my gym outfits throughout the cooler months."
"Love this jacket â¤ī¸â¤ī¸â¤ī¸:hands_heart:"

"Obsessed with this jacket. Hugs you in all the right places. Need one in all the colors. Waiting to see if the brown will be restocked."
"So comfy, true to size, good quality and reasonable price. I’m very happy!"
"I am xs-s in csb pieces, bought this in xs and the fit is just right. I have quite slim arms and small waist otherwise I would size up. Love the quality, doesn’t feel flimsy"
