What style of clothing is inexpensive but looks high-end?

Girls don’t need to wear expensive clothes, just about the same. They should be decent and suitable for you. The color matching does not violate the harmony. Wear professional clothes at work to make you look solid and capable. Don’t wear casual clothes too much in front of your boyfriend. It is fat and looks watery. After matching your clothes, don't forget your hair. Don't let your hair be greasy. No matter how long or short it is, it must be tangible to be energetic. Then it's clean and not sloppy. In a word, the clothes are not afraid of being old, but they are afraid of not fitting. If you have a good figure, a fine hairstyle and a delicate face, if you wear old clothes, people will think that you are deliberately looking old.
