[Nightshade]

I actually had no idea what you were talking about so I took your reddit link ( never heard of reddit before) and had a look. To be perfectly honest, at this stage of your development I don't think you would have a cat in hells chance of fooling anyone in that collection of extremely curvy ladies. No bra or insert could ever make you, or anyone else on here, look like them, much as we all wish we could.
Sorry, but you asked for honest thoughts.
Now, having said all that, the third one of your pictures does seem to show the start of some breast development, probably about average for 6 months, so I'd just carry on and enjoy the journey, if I were you.

Thanks. It wasn't solely on the basis of my breasts. I know they're small. When I look in the mirror, the curve of my stomach does look like I have wide® hips, but in the photo it seemed a lot less pronounced. I think of curvy more as an hourglass figure than just big jugs. And they even say crossdressers can post, but some genetic males have more feminine bodies without hormones than others on HRT.

I have seen pics of women where they lean to one side to make their hips look bigger (and maybe their stomach smaller?), but without more chest there's no amount of camera trickery will help. I think also having wider shoulders and an overall male looking body counts against.

This isn't the best example, but it does show some things that can be done with posing: https://brightside.me/inspiration-tips-and-tricks/11-tricks-to-perfect-posing-for-girls-with-curves-395510/
