Q&A for How to Make Fake Breasts

You can engage in athletic activities, but your experience will depend on the specific sport and the type of fake breasts you are wearing. For less intensive sports, a stuffed bra may be adequate, while a breastplate should offer greater security for more vigorous activities. It is generally advisable to avoid swimming, regardless of the type, as most fake breasts are not designed for water submersion.

Yep! If you're stuffing, you can get a bigger bra and fill it with as much tissue paper or as many socks as you need. If you're making a breastplate, instead of using 2 smaller bra cups to make each new cup, try using 3 or 4.

You might find that creating fake breasts is often for purposes like costumes or theatrical productions. These uses are generally not intended to be offensive and serve various creative and practical needs.

If you're not trying to pass them off as real, it doesn't matter. If you do want people to think they're real, either refrain from hugging anyone or try to stick to a side hug where you're not pressing your chest against theirs.

Yes, just use smaller cups.

Yes, it is entirely likely that you will be teased over this. If you decide to make and wear these, just be prepared that many people will not understand and may tease you about it.

use two shirts, one as a over-shirt, the other as a improvised bra (tuck it around your filler material and adjust and experiment with it) you might want to tie (or sew it if your good at that) things together to make it stay, just don't get stuck in it and have to tear it apart to get out (but really if an opportunity to get a bra comes, get it, it works so much better, especially if it fits right)

You could put your material in bags or inside balloons if it works. Put them in a bra that is meant for swimming and can get wet. Any other watertight containers that allow flexibility work too.

Find a padded bra (possibly a push-up bra). Then get some party balloons and fill them with water; just enough for them to be put in the cups and be comfortable. Make sure there is no air in the balloons, then tie them shut. Put the balloons in the cups, wear something over it, and that should be what you need.

Stealing is wrong. When you steal from your sister, especially something as intimate as her underwear, you risk irreparably damaging your relationship with her. So yes, it is wrong. You can get your own bra, some of them are not too expensive. Or, ask her. She may have an old pair she doesn't care for anymore and can give you.

Yes, it's similar to using the circles cut from a spare bra, as described in method 2.
