0. All one's clothes should fit as exactly as possible, and this is especially true for structured dresses like this one. Get them tailored if you feel they could be taken in a little, the cost is usually minor but the rewards are major.
1. The current weather in San Francisco is a nice middle ground for wearing outfits like this. SF lacks the extreme cold climate of Northern/Eastern states that require heavy winter gear. SF also lacks the Southern California warm temperatures that render coats and warm fabrics unnecessary.
2. The back seam tights are a nice vintage style element. It works in this outfit because the cut of the dress and coat are clean and modern, so the entire look isn't a vintage costume, it's a contemporary outfit with vintage inspirations.
3. The exquisitely detailed watch is my favorite detail in this outfit. Dyanna and I often notice the way even the smallest accessories enhance an outfit's overall beauty.
Think of it this way, a good outfit is one beautiful note. It's like hearing one musical instrument or tasting one single flavor of a dish. When you add appropriate accessories, you get to hear an entire band, or savor several harmonious flavors in a dish. You get complexity and depth!
