Don't worry, your height is relatively high, so your clothes won't be too small. You can ask the manager who distributes clothes to give you a slightly larger size, which doesn't suit you. Now you can wear a body-shaping underwear, tighten your abdomen, and you will look much better when you wear clothes. It doesn't matter how big your ass is! Etiquette pays attention to appearance, temperament and posture. Confidence is very important! Come on!
