Q: How do you know when you need to go up a cup. I'm wearing a 36A but I think I might possibly be a B. My boobs dont have much more room in my bra. And sometimes it feels like they can fall out. so heres my question how can you tell when you need to go up a cup??? Thank U
A: I think you just answered your question. if you feel like you could be falling out I think it's time to go bra shopping. Go shop around and try a 36b and see how it fits.. if you don't fill it out try half cup sizes.
