If you feel that it would make you more comfortable with your body then you should definitely try it! Seriously, just go for it if you have a big chest or not. I think it’s different for everyone because peoples body sizes/shapes and relationships with them are different.

I have a small chest so it’s pretty much been all positive for me apart from the fact that I’m fat and sometimes (it depends on what I’m wearing) you can tell that I am wearing a binder. I definitely think you should try looking through some tags or maybe try searching a few videos on YouTube though.

There’s this video: http://www.youtube.com/watch?v=3vAuyCrRU_U

They mention that they wear anything from a C - D.

And this one: http://www.youtube.com/watch?v=WfhTzBdnv0g

They mention they’re an F cup but use velcro binders and I don’t know how good they are for you but I’ve read a lot of positive reviews on Underworks binders.

I hope this helps and I hope you come across some people with a similar size chest who bind so you can maybe hear their experience.

Good luck!
