I go braless all the time! I was excited to maybe give some helpful feedback but the look you’re trying to go for sounds a lot different from what I wear. So here’s a dumb joke answer I write instead

If you love a shirt but don’t wear often because it doesn’t compliment your figure or perhaps it doesn’t show off enough sideboob, pay someone on Etsy to alter it for you and show off that sideboob to the world

You can get dresses like this for pretty cheap actually! Holds everything in
