How to choose a bra when wearing a backless outfit?
1. Breast wrapping
The first one is that you can use breast wrap instead of bra, because the style of breast wrap can already be exposed outside. If you are wearing white clothes, you can pair them with this white chest wrap to make it look less abrupt. If you are wearing colorful clothes, I think you can also wear black chest wrap because after all, black is everything.
2. Backless bra
And the second method is backless bra. There are specialized backless bra on the market, but they are designed to look good on the back and have an artistic feel when exposed. So I found these pictures for everyone to see because I don't have them on hand, so I want to show them to everyone. It looks like this, and the back looks sexy and innovative, so I think this is a good choice.

3. Transparent shoulder strap bra
Then the third method is transparent shoulder straps. If you don't need the messy things at the back, you can also choose underwear with transparent straps at the back. This type of underwear is more suitable for viewing from afar or taking photos, but if you look closer, I personally think it is more obvious. Moreover, this transparent plastic is not particularly attractive, so it depends on your personal preferences.
4. Invisible bra
The fourth method is if you prefer to have nothing on your back, you can choose an invisible bra. It's actually quite popular now, there are quite a few lingerie stores selling it. I have bought one before and worn it several times, but to be honest, wearing it in summer is really uncomfortable because it makes me sweat easily. Moreover, the inner layer of it was originally sticky, so it felt like it was sticking all over your chest, which was quite uncomfortable.

5. Nipple cover
The fifth method is nipple cover. Nipple covers are just a small piece, used to stick them on the front to prevent you from missing anything. However, I feel that there are still relatively few people who use this, mainly for model shows or when a little sister with a good figure wears very hot clothes!
