First of all, the height of 165 is really short for boys, and 54 kg should look a little fleshy. I suggest buying a suitable dress with a pair of leather shoes and, if possible, a raised insole. The height is too short, it will look better when photographed. As for the color of clothes, choose black. Remember to try on this dress, otherwise it will make you look shorter if it is loose. It doesn't matter if your hair is taller and you have insoles ... As for shirts with bottoms inside, it's best to choose a body suit, and then it will be just right, a little loose, but don't choose shirts that are too tight.
