"sooo good. colour style fit is perfec"
"It’s so beautiful! It gives you a lovely vibes with a spicy touch. Despite of that , It is too showing. Not much coverage for a big breast . I’ve tried to size up and it was okay in the breast but huge in the shoulders. I decided to stay with size S , but I don’t feel it’s okay for a gym sesh or pilates /yoga . CSB could improve and be more inclusive with the pétit ones that have a body type more curving?! 🤍I have returned so many crops because of the this issue. Ps. Quality and fashion is always amazing. I’m 5’1 feet"
"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."
