"Fantastic cut!! But you gotta size up on this one for sure! It’s quite a bit of side boob even after sizing up but the fabric really holds you in and the paddings help. This but in form fabric would be amazing"
"Beautiful color and fabric — it’s super soft and flattering on. The material feels really nice quality and the color is gorgeous in person. My only negatives are that it definitely runs small, so I’d consider sizing up, and beware of side boob depending on your chest size. I originally thought it would be great for workouts, but for me it’s more practical for running errands or athleisure wear than actual gym sessions."
"I personally didn't like the style - it is too low coverage and I found even my AA boobs spill out the side somehow. I wouldn't be comfortable wearing this to go out and definitely not to the gym. Also the sage colour washes me out. Much prefer the darker/bolder colours for my skin tone. Returned this one!"
"Should have listened and gotten a size bigger. It's still fine to wear if I push my boobs in but it's true that it runs quite small and has noticeable side boob. So if you're a B cup or larger, definitely take note of this and get a bigger size."
"Personally I thought this went down a bit too low on either side and wasn't enough coverage for me to be comfortable wearing it anywhere. Also, sage is not my colour - would love CSB to come out with a deeper cool toned green!"
"I really love this demi top. Planning to buy this in espresso color too <3"
"The Serenity Demi Tank in Sage was part of my first CSB set I really like the fit — it feels comfortable, flattering, and easy to wear for workouts or everyday looks."
"I love the sage color, it's so pretty! The tank is very nice and comfortable, just the right length. I like that it's padded. The fabric is really soft. Only thing to be aware of is that it's cropped on the sides (shows side breast a little bit)."
"I love this tank. The Serenity Demi Tank in Sage is the perfect balance of supportive and flattering. The fabric feels soft but still structured enough to hold everything in place during Pilates and low-impact workouts. The color is beautiful in person — a calm, muted green that pairs easily with different leggings and wraps."
"Love how comfortable it feels"
