Tucking in a shirt when wearing an office skirt with belt loops can be a little tricky, but here are the steps to follow:

1. First, put on your skirt and make sure it sits at your natural waistline.
2. Next, put on your shirt and leave it untucked.
3. Fasten your belt through the belt loops on the skirt, making sure it’s snug but not too tight.
4. Smooth out the shirt so that it lays flat against your body.
5. Grab the fabric at the sides of the shirt and tuck it into the skirt at the front. Make sure the fabric is evenly distributed and not bunched up.
