What size shoul I order if I'm 36D!?

The pictures of the model with the white shirt has a completely different bra on. You can see the clasp under the tie of her shirt. Why?

How thick is the padding? I’m small chested, so I was hoping for at least an extra cup size lol

I am a 38d. Your sizing is confusing. Which size would I need ?
