     I want you to imagine how the technical flat sketch of the garment you see in the picture would look like, and describe it in rich details, in one paragraph.
     Don't add any additional comment.
-    Specify that the flat sketch is black and white (even if the original garment has a color), that it doesn't include the person that wear the garment, and that it's not made on a paper sheet, but it's digitally made, so it has plain white background, not paper.

     The style of the result should look somewhat like the following example:
     The technical flat sketch of the dress depicts 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 elastic neckline sits straight across the chest, ensuring a secure fit.
     The bodice transitions into a flowy, tiered skirt with three evenly spaced gathered panels, creating soft volume.
     Elasticized areas are marked with textured lines, while the gathers and drape is indicated through subtle curved strokes, ensuring clarity in construction details.
     The flat sketch does NOT include any person and it's only the in black and white, being a technical drawing.
