This is not a finished pattern. It is a streamlined drafting base generated from your exact measurements (or using our provided ASTM size table measurements) and fabric stretch properties.\u003c\/p\u003e\n\u003cp data-end=\"1181\" data-start=\"889\"\u003eThe block transfers traditional dart shaping into a curved princess seam that runs over the bust and down the torso. Instead of visible darts, shaping is built directly into the seam line, creating smooth contour through the bust, waist, and hips while maintaining a clean, minimal structure.\u003c\/p\u003e\n\u003cp data-end=\"1499\" data-start=\"1183\"\u003eDesigned to be light, agile, and flexible, the Princess Seam Block acts as a blank canvas for designers. It provides accurate body shaping without locking you into predefined style decisions, allowing you to develop your own necklines, straps, seam placements, and design details directly from a balanced foundation.\u003c\/p\u003e\n\u003cp data-end=\"1776\" data-start=\"1501\"\u003eBecause the block is generated from your exact measurements, it automatically carries your unique dart value. Small bust, full bust, or anywhere in between, the shaping is already built in. No bust adjustments. No extra math. Just a precise base ready for design development.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003c\/section\u003e\n\u003ch3\u003eBlock Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eControl the height of the leg hole (0% closer to the waist line, 100% sitting at the hip line). This helps you control the level of coverage, as well as, the stability of the garment in wear.
