For various reasons, college girls have different consumption choices. You need high-end fashion, and your position should be that part of female college students with strong spending power and relatively rich economy.

As a non-professional decorator, I can only say: you get what you pay for, and you will soon be hungry after eating porridge.

In order to save costs, my suggestions are:

Go to the building materials market by yourself and pack materials when decorating.

Wall paint should not be wallpaper. It is enough to choose the same grade of products for wall paint.

It is best to consult the merchants who sell lamps when choosing lamps. In a clothing store, the effect of lighting is very important, just like PS photos.

As for the overall style, I don't know. There are many styles of clothes (especially women's clothes), and the decoration style should be unified with the clothes you handle. I don't need to tell you the effect of assembling a pair of Adidas XX limited edition sports shoes in the famous brand West.

Renderings? ! Sorry, I don't know the height and depth of your store, so I can't give it to ... It's a design problem, and we can only give a plan if we know the specific situation.

Fashion is high-end, this mainly depends on design. Decoration saves money, which mainly depends on your material selection.

As a colleague similar to you, a non-professional decorator, these are the experiences I can provide. You can refer to them and hope to help you!

I almost forgot that a good LOGO is also extremely important. An excellent LOGO will bring you more business. I suggest you design one well.
