Hoping to maybe get some insight in the vest sizing. I ordered a S/M per the app’s recommendation. However, I feel it’s a little big based on how I could afford to tighten the top two straps more if there was room to do so. Trying to see if anyone is similarly sized and is in the XXS/XS. I’ve posted my normal sizes in the two bras I buy and they’re aligning with the XXS/XS but looking for anyone who thinks it fits differently. I’m a 6 in the Flow Y Nulu and an XXS/XS in the Bend This Scoop. Also including pictures of me in the vest.

Thanks in advance for any advice :)
