I ordered the Kangzhu cups in small recently and realised that because of how my ribcage is crooked and my small build, the kangzhu cups won't fit on my left boob. It's not an urgent problem since this is the bigger boob, but ideally I'd like to be able to pump on both sides. It's really annoying because I can't fit the cup on the right unless I'm lying down, which I doubt is optimum for boob growth lol.
The cups just kinda jut out at the sides and don't have enough body area to create a vacuum (idk how to explain this) but I'm wondering if there is any way to overcome this? I foolishly purchased a large beforehand just because I saw it came with a pump and the small didn't, and obviously it didn't fit, so I purchased the small.
