Ok I found the BEST SOLUTION! I hope everyone that gets a new sternum tattoo sees this I got mine last week and I have a ton of unpacked sports bras from Victoria Secret and I literally used a hair tie and tied it around the front of my sports bra while I have it on and it scrunched up the sternum area of it so it doesn’t touch my tattoo and it’s perfect I’ve been wearing different bras all week and it never rubs!
I did it by putting a hair tie inside my sports bra and pulling one end of the hair tie through the bottom and top part of my bra. Then I loop one end of the hair tie inside the other end and pull it tight then I grabbed one of the knots I made when doing that and put my hair tie under it and pulled again so that it would stay in place and boom it’s perfect!
