A tank top is an easy refashion, especially if you use an existing tank that you like the style of as a pattern. Cut slowly right below the collar seam.
I tested out five different styles:
How to cut a shirt into a v neck. It's easy and takes less than half an hour. Identify where you want the v to end and mark the sweatshirt at this point. Place it so it lines up with the top edge of the shirt on the front and the back of the neckline you cut.
Cut just beyond the topstitching to create a clean edge for the steps that follow. You only have to mark one side of the highest point. I was excited, but i despise crew neck shirts.
Position your scissors at the point that you marked and hold the fabric taught. The hoodie neckline will be facing upward and the hood will be on the backside. Make sure they are aligned.
Connect the slit to the cut edges of the side seams using angled lines. Measure 2 down the center of the shirt and pin it. Cut across the back of your shirt (not the front), 6 inches (15 cm) above the hem.
First, using scissors, cut off the band around the existing neckline. Put on your crew neck tee and mark with pins or tape where you want the lowest and highest points of your v neck to be. Pin the neckband back onto the right side of the shirt, along the newly cut neckline, with the raw edges together.
This makes it so 1 inch of the new fabric piece is visible on the front of the sweater while 1 inch is visible on the back of the sweater. I also trim large boxy sleeves into a more feminine cut. Fold 1 inch of the shirts neck back towards you.
Fold the shirt in half lengthwise and lay it flat on the table. The lower you cut the back of the neckline, the lower on your back the bow will be. Iron the hoodie to remove any wrinkles.
Take off the shirt and fold the front of the shirt on itself longways. Next, cut a small slit into the middle of the hem in the front of your shirt. If you cut deeper than 2, you may need more fabric (which can be constructed out of what you cut off).
The neckline that was just cut off can be discarded. Align the seams at the front and the back so they match up. After you’ve traced the v, use sharp scissors to remove the stitches securing the front of the collar.
Sew the trims on once you are sure they are exactly how you want them! Then, identify where you want each side of the v to start and mark the sweatshirt’s neckline to indicate where you will begin cutting.
