A basic T-shirt may be any girl's go-to garment for a casual day, but why keep the style so simple? Ribbed crew necks aren't always the most flattering choice for necklines, and they don't transition easily from a day look to night, especially if you're hankering for something a little hotter. You don't need to clear your closet of unfashionable crew-neck shirts, however. Instead, turn those tees trendy with a quick T-shirt neck shape surgery.
Determine the type of neckline you'd like to make on your T-shirt. You can turn the shirt's basic crew neck into a scoop, V, boat or any other style you like.
Put your shirt onto a dressform, inside-out. Draw the neck style you want directly onto the shirt with a fabric pencil.
Draw the neckline again, this time 3/4 inch in from the original line. This will give you a 3/4 inch allowance of fabric. Cut along this line.
Fold the neckline 1/4 inch to the inside of the shirt. Iron the fold flat.
Fold the neckline another 1/2 inch to the inside of the shirt, hiding the raw edges of the fabric. Iron and pin it.
Sew around the new neckline, along the lower fold.
Instead of creating a neckline hem to cover the raw edges of the fabric, you can also sew binding directly over the cut neckline.
Make sure you are using the correct stitch for the type of fabric your T-shirt is made from. A basic stitch works well on many fabrics, but stretchy knits require overlock or zigzag stitching.
