Being fashionable is not limited to what you wear whether clothing, shoes, accessories and bags. You can also be fashionable at home and at work. Your surroundings can be your own and it does not have to be what others like. It is what you like. If you are happy with it, then go ahead. If you desire it yet your budget is not yet enough then save for it. You only live once so make the most out of life. Be happy especially if it does not take you to step on others’ happiness.
Whether your bed linen jives or not with your curtains does not have to be an issue. Some people are OC with matching everything from bed covers to pillow cases to curtains. Towels will even match, if not the design, the color will. The wall may not be easy to change in color but in the first place they will have it close to what will match most of their stuff. Others, on the other hand, love variety to the extent that nothing matches at all. The bed linen may be white and two pillow cases with different colors and the blanket is of another. That’s just how different minds work. The fashion of one’s own.
