Another perspective is to remember that just because you love something (the one turquoise nightstand) doesn't mean you need more of it (an entire matching set). Take a moment to think about how having such a "matchy matchy" set will feel. Having an entire room of refinished vintage turquoise furniture can be as boring as an entire "Rooms to Go"/Right Outta the Showroom set - both options lack interest because there is no contrast. No story. The very best rooms, in my opinion, come from collecting disparate pieces and putting them together. Want verification? Check Pinterest, Apartment Therapy, home design blogs, etc. Matchy-matchy - even when its super cute and vintage - won't convey as much interest as a carefully placed vignette of items collected from Goodwill, thrift stores, Craigslist, etc. with a single turquoise nightstand.
I'm interested in vintage/antique furniture and care deeply about the aesthetics of my home. Some mustachians seem to forgo any interest in their furnishings, but I definitely believe surrounding yourself with things you love is a worthwhile endeavor. However, I'm just as likely to pick up a chair off the side of the road as I am to drop $ at a fancy antique mall, if it meets my needs and aesthetic sensibilities. But I've learned several things about well designed spaces:
1. Less is usually more (any designer will tell you editing is the hardest part)
2. Be patient - there's a temptation to fill all your furnishing needs IMMEDIATELY, but by living in the space for a while, your needs might change and evolve. Rather than a dresser, you may end up finding out you don't have enough clothes to justify a large one and can get by with some other piece.
3. Keep your big purchases timeless and flexible and save the trendy colors for accent pieces - will you love turquoise forever? Will you want to replace your entire bedroom set if in 5 years, vintage beach-themes are out and sunset orange is in?
