Need some help here plz ladies!!

This is kinda hard to explain and I’m really opening up and reaching out which is hard for me to do so please bare with me. To start off with I’m Italian, Dutch and a few minor other things. So I’m short and petite by nature due to genes. On my Dutch side I have a decent butt and decent thighs. But my Italian side I have a small but decent mid area and smaller boobs but I’m not an A cup.

Here’s where it gets hard for me.. I’m extremely bad when it comes to my body. As in I’m not happy with it but I don’t dislike it. I know sounds odd but it’s my chest size. I know I can’t change it unless I have surgery and I’m not doing that. I’ve been exploring bras. I wear a normal bra without padding and underwire. My fiancé tells me to not change to please him because he loves me the way I am. Yes he likes bigger boobs. He likes to please me as i him. But I’m mainly doing this for me. I’ve struggled all my life. Not due to anyone. But I’m new to this who padded bra thing. Could anyone give tips or any kind of advise..? I tried my normal size but somehow it didn’t feel/fit right.
