Most men's button-down shirts are designed to be a bit long so they stay tucked in. But when you want to wear shirts untucked for casual events, they can look unkempt and sloppy -- the perfect length for an untucked men's shirt is halfway between the belt and the bottom of the zipper. If you know how to sew a straight line, you can easily shorten your own shirts.

Things You'll Need
Iron and ironing board
Sewing machine with a universal 90/14 needle and thread
Put on the shirt and use a pin to mark where you'd like the new hemline to fall. Take the shirt off.
To determine how much of the shirt to cut off, measure from the bottom of the hem to the pin. Subtract 1 1/4 inches from this measurement to allow for a hem. For example, if your new hemline is 4 inches from the bottom of the existing hem, then 4 - 1 1/4 = 2 3/4. You will mark 2 3/4 inches from the bottom of the shirt. Use a measuring tape and a washable marker to mark the cut line across the bottom of the shirt.
Cut along the line you marked.
Fold the raw edge 1/4 inch under toward the inside of the shirt and press with an iron.
Use straight pins to pin the pressed edge in place.
Use a 90/14 needle and a medium stitch length to sew along the pressed edge. Be sure to remove the pins as you sew.
Now fold 1 inch under toward the inside of the shirt and press again with an iron.
Pin the pressed edge in place.
Sew along the previous stitch line to create the hem, removing the pins as you sew.
Now when you untuck your shirt for a more casual look, you will not only have comfortable access to your pockets, but you can show off your jeans without looking frumpy or disheveled.
