I found that Spectrum Outfitters worked best for me (prices range from $50-$39). I also have binders that are older and stretched out or that don’t work as well (like gc2b) that I use when I don’t need as flat of a chest because they are easier on my rib cage lol. If you do that, do NOT count that as a break!
Don't bind for more than 8 hours
Don't exercise in a binder
Try to only wear a binder for 5 or 6 days a week (this one is hard, I know)
If it hurts, take it off!
If you notice bruising, something is wrong! Your binder might be too small or you may be wearing it for too long.
Wearing binders all the time is not too good for you so I recommend using a variety of different binding techniques. One is TransTape!
The reason Ace bandages are unsafe is because as you breathe it gets tighter and tighter and can really hurt you. But TransTape doesn't do that, it's like the tape athletes use when they sprain their ankle or something. It's safe as long as it is used properly. Plus, you can wear it for up to 5 days, exercise and sleep while wearing it, and it's water proof!
TransTape isn't the only brand of course, but they do have a lot of great resources.
Learn more at their website here. I recommend starting with this page and the FAQ.
KT tape is another option if you cant afford/arent allowed to order TransTape. You can find it at most drugstores and box stores for relatively cheap. The adhesive isnt as strong as TransTape, keep that in mind when applying.
Men's Compression Shirts *I have not used these myself (yet) but I hear they work pretty well*
Made for cis men with gynecomastia but hey we can use em. Obviously will work much better for smaller chests, but could still do something for bigger chests, maybe for under a hoodie?
They won't flatten you as well as binders but the goal is more to masculinize the shape of your chest than to completely flatten it. They are also safer than binders.
The color black will make you look flatter
Layers! Lots of layers! (don't overheat)
