A. 21 in.
B. 36 in.
C. 27 in.
D. 54 in.

I'm sorry you're in a class against your will -- but we will not help you cheat.

But like where am I supposed to find this stuff out? They just gave me online exams and no information whatsoever about these things.

I can't believe that your course doesn't have a text or at least recommended reading materials. If it doesn't provide you with information, get out of that school FAST!

1. To find the length of material needed for the dress portion of the outfit, we need to add up the various measurements. The front skirt length is 20 in., the full back length is 41 in., and we also need to account for the seam allowances and hem. Let's say we add an extra 1 inch at the top for the seam allowance and 2 inches at the bottom for the hem. Adding all these measurements together, we get 20 + 41 + 1 + 2 = 64 inches.

However, the fabric comes in a 36-inch width, so we need to double the length to account for the front and back of the dress. Therefore, the total length of material needed for the dress portion is 64 in. x 2 = 128 inches.

2. For the jacket sleeves, we simply need to take the jacket back length of 15 inches and multiply it by 2 to account for both sleeves. So, 15 x 2 = 30 inches.

3. To test fabric for shrinkage, you can cut a small swatch of the fabric and wash it according to the care instructions on the label. If the label does not provide any instructions, it's best to wash the fabric in cold water to avoid any damage or color bleeding. After washing, you can measure the swatch again to see if it has shrunk. This will give you an idea of how much the fabric may shrink and help determine whether pre-shrinking is necessary.

4. The shaping technique that adds shape to a bodice is called darts. Darts are usually triangular or diamond-shaped folds of fabric that are sewn together at the apex to create a three-dimensional shape. They are commonly used in garments to provide contour and shape to areas such as the bust or waistline.

5. If the side seams of a skirt curve towards the back when the client tries it on, it indicates that the skirt back is too loose. This means that there is excess fabric or that the waistline of the skirt needs to be taken in to achieve a better fit.

6. When attaching a 1/2-inch button, the size of the buttonhole should be slightly larger to accommodate the button. A suitable buttonhole size would be 5/8 inch. This allows for ease of buttoning and unbuttoning without being too tight or too loose.

7. If you're working with a fabric that frays easily, the best buttonhole option would be a bound buttonhole. Bound buttonholes create a clean, finished look while also reinforcing the buttonhole edges. They involve cutting and folding fabric strips to create the buttonhole edges, offering extra stability to prevent fraying.

8. When attaching a button on a man's overcoat to reduce heavy strain, the best option would be to reinforce the button with a smaller button on the inside. By sewing a smaller button underneath the larger button, you distribute the strain and reinforce the button attachment, reducing the likelihood of it coming loose or breaking.

9. The best time to make alterations to a garment is on the pattern pieces before sewing the garment. By making alterations on the pattern, you can ensure a better fit and make any necessary adjustments to the overall shape and size. This saves time and effort compared to making alterations after the garment has been sewn.

10. Fabrics that have difficulty pleating well are those that are too lightweight or too stretchy. In this case, the fabric that would have difficulty pleating well is jersey. Jersey is a stretchy knit fabric that tends to drape and flow rather than hold crisp pleats. Fabrics like wool, cotton, and linen are generally easier to pleat as they have more structure and hold their shapes better.
