Motiva ergonomix implants. What size?

I'm having a breast uplift and BA soon, I've chose motiva ergonomix (under muscle) but i am unsure what size to get.

I'm 11st, 5ft 6 and I'm starting out with next to no breast tissue.

I'm thinking anywhere between 255cc - 315cc as i don't want them too big, but I do want them to be noticeable.

Would anybody feel comfortable sharing pictures of their implants that fit this category? Hard to find anything solid online

TIA
