There's no one answer to this question since everyone's VSCO room (or VSCO grid, as it's sometimes called) will be unique to their own style and taste. However, there are a few tips and tricks you can use to create an aesthetic and cohesive VSCO room that reflects your personality.
First, consider the overall color scheme of your room. VSCO rooms tend to be fairly minimalistic, so a neutral palette is usually best. Once you have a general color scheme in mind, start adding in some key pieces that will help tie the room together. A comfy chair or bean bag, some cozy blankets, and some cute pillows are all great additions.
Next, think about the layout of your room. VSCO rooms are typically pretty clean and organized, so try to keep that in mind as you're arranging your furniture. You want your room to look effortless, so avoid clutter and try to keep things tidy.
Finally, add in some personal touches that will make your room feel like home. This could be anything from photos and art to sentimental items that remind you of happy memories. By adding these personal touches, you'll create a space that is both aesthetically pleasing and personal to you.
