Bralets have this nice vintage/retro look because they sort of resemble the top half of a halterneck rockabilly dress like the one below.
With any sort of outfit, balance has to be present. Without it, the outfit doesn't work. For example, if you're wearing a baggy or loose top then you should wear tight bottoms; if you're wearing a patterned dress then you should wear plain shoes and socks or tights. With bralets, if you're going to wear one then the bottom half of your body should not be exposed as much as the top.
You have to have a certain amount of confidence with your body and yourself in order to wear a bralet confidentally. I don't have this confidence and my skin is not nice enough to put on show.
Some bralets are way too revealing but there are those that look similar to corset tops and are actually quite nice.
Like I said, I don't think they should be worn by anyone younger than 16. It doesn't feel right or look right and you know that, at that age, they're just asking for attention. I know because I was 15 a couple of years ago. I dressed to impress as much as I could and I had an army of cropped shirts to help me. I still have those shirts but now I wear them with something underneath...
That's all for now. Stay beautiful x
