"I don’t know if it’s just me but a lot of the CSB crops come up and don’t sit underneath my boobs properly especially the halters. The form gia is great and the Lexi but this one unfortunately continually rode up. Please bring back but add adjustable straps!"
"Such a cute pop of colour BUT runs very small, I am usually an XS and had to exchange for an M."
"This top is super cute, but the halter can get really uncomfortable after wearing it for too long"
"so cute and pretty"
"It runs a littttle small, I’m 155cm and 43kg for reference m. I probably won’t recommend this to anybody who has a long torso as the crop is rly crop but bc I have a short torso I think it’s p flattering, might have been better if I upped a size but I still love it"
"Such a great top in a really cute colour! But, I had to size up from an xs to a m, and could even go a size bigger. Overall though, super cute and a great colour!"
"I love this Strawberry color! Its great for the spring/summer, The design is super girly and flattering."
"Love the style, a little small on the coverage side of things. Did a HIIT class and got some underboob oooops. Will just be wearing for lower impact activities. Maybe if I I went up a size it could have been a bit of a better fit, unsure!"
"Ok this might be one of my fav sports bras ever HOWEVER this top runs VERY small compared to their other sports bras!!! I normally get an XS in CSB bras but my girls were not staying in at all so I had to exchange for a S, haven’t tried it on yet but I know it’ll fit."
