You will need: A shirt (preferably a size larger), scissors, and a mirror.
I bought this shirt online and I really like it!
The only problem?
When you are finished, the back of your shirt should look like this (I just put that wooden stick there so you can see what I did).
So now, make a little cut on the bottom of that top section on the bottom on the middle. Just about where I pushed the fabric up in this photo.
Your back should look like this.
This is where you can alter your neck line. You can keep it as it came when we cut the ribbed fabric off the neckline, or you can cut it into a "V" neck, or a sweetheart neck, or whatever. For this tutorial, I'm cutting it into a sweetheart neckline.
Basically, put on a bra. Start at your cleavage (in the middle of your boobs) and determine how much of your boobs you want to show. If you want lots of boob-age, cut the neckline lower. If you want to cover it up, start a little higher. It's safer to start higher and cut lower as you go on. Cut from that center following along the top of your bra cup (towards your armpits) till you get to your bra strap, then cut going straight up to your shoulder. Do the same to the other side.
I hope you liked this tutorial! Happy cutting! <3!
