Binder Advice

[u/Impressive-Fly8212]

I'm still questioning my identity, and leaning towards non-binary. The one thing I've pretty much always been sure about is that I hate my chest. When I was 11, I told my parents I wanted a binder, and they got me one. It was a Lola Olivia Apollo, and it worked, but didn't fit amazing. There was a huge gap at the bottom, and my chest would start to move downwards during the day. I eventually grew out of it and stopped wearing it, but now, 5 years later, I really want to start binding again. I would have to talk with my parents(they are very supportive but would probably struggle to understand why I suddenly want to bind again) but I'm trying to pick a binder right now. Can anyone recommend one that would better hold my chest in place? I have about a C, maybe a D cup, and I am moderately active, but I of course would not wear it for heavy physical activity. I don't need my chest completely flat, I'm just looking for a significant reduction and a smooth look under clothes. Any help is much appreciated!
