On very small pieces such as doll clothes, on small detail pieces such as belt carriers and in larger areas where you would need to trim away the excess seam allowance; we typically reduce the seam allowance to 3/8" or 1/4" to make your sewing easier.

Response: For me the motivation to use the Bunka sloper is that it is the base used to draft all the wonderful garments featured in the Ms. Stylebook and Lady Boutique magazines. And the sloper drafting instructions, which are diagrams rather than words, can be understood without reading Japanese. There are pattern drafting books available in the USA, but the garment styles included in those books are basic, limited, and are of the time the book was published. As you guessed the Bunka Asian sloper (either from the preprinted magazine insert or drafted from my measurements) still needed some changes to fit my taller, middle aged, non Asian body properly. But after making those changes, I have a sloper I can use to draft the magazine patterns.
I liked the fitted silhouette of the dress and came up with several options for the neckline trim. It was shown with the neckline trimmed with fur. I had an old mink collar I considered refashioning into fur trim similar to that shown in the picture. As another option I considered adding neckline flounces in a sheer sequined fabric. This idea came from a picture of a dress worn at the Melbourne Race posted by Gail
But in the interest of time, what I ultimately ended up using was a premade trim of faux jewels and sequins. It came in a curved piece that was pretty close to the dress front neckline curve, and straight yardage which I used on the back neckline. The trim was on sale for about $4.00, probably because the faux jewel fad is fading or perhaps over, but it worked for me in terms of cost and ease of application. I hand tacked the trim in place so it will be easy to remove and replace with a different trim.
The dress fabric is a lightweight wool crepe and it is lined in red and black print silk twill. It was very easy to accessorize with sheer hose and strappy sandals.
