Q. What is the proper posture one should have when sitting, standing, walking, etc.?
A. An excellent topic! Posture is a very important part of appearance. A slouchy posture affects your appearance in a negative way, and pretty posture enhances beauty exponentially!
When sitting, your posture should be such that you are sitting directly on top of your "sitting bones." Your shoulders should be back but relaxed, and your ears should be directly over your shoulders. Avoid any arch in your back; your legs and back should be at a ninety degree angle.
Slide down into your seat gracefully. Depending on the length of your skirt, you can cross your legs at the ankles or cross your legs at the knees. Shorter skirts make it absolutely forbidden for you to cross your legs at the knees, and it is generally considered more proper to cross your legs at the ankles, no matter your skirt length. You can also leave your feet flat on the floor and together, either side by side or one sightly in front of the other. Your hands should be in your lap and possibly to one side rather than in the middle.
When standing, your posture should still be tall and upright. Pin your shoulders back and move your head back so that your ears are over your shoulders. Hold your stomach in, and tuck your hips under as you walk. Take smaller steps and keep your feet under you and close together. This will help avoid a boyish gait and make you appear polished and poised.
As you practice good posture, be confident, wear a smile on your face, and remember that beauty comes from the Lord! Your inner beauty will shine forth as you endeavor to hold high the character and appearance that God has blessed you with!
