The very first thing you have to do to bring that luxurious feel into your home is to eliminate clutter. This is counterintuitive because most people find it very easy to go overboard with accessories. Instead, try to be more purposeful with how you decorate your home.
To begin with, get rid of all the extra furniture you don’t need. If it doesn’t serve any meaningful function, then you’ve got to let it go. Once you’re done, take care of the accessories. Accent pieces should come in threes: three pillows on your couch, three colored glass bottles on your entryway table and so on. When you’re done with the rearranging, you can get a sense of the feel of the room, tweaking what needs to be tweaked to make everything feel a little more balanced.
