+                            The technical flat sketch of the dress would depict a midi-length, off-the-shoulder design with a smocked bodice and short puff sleeves that have elasticized cuffs. The elastic neckline sits straight across the chest and back, ensuring a secure fit. The bodice transitions into a flowy, tiered skirt with three evenly spaced gathered panels, creating soft volume. The back view mirrors the front, maintaining the smocked fit and tiered skirt without visible closures, suggesting a pullover style. Elasticized areas would be marked with textured lines, while the gathers and drape would be indicated through subtle curved strokes, ensuring clarity in construction details.
