Answer

Pages 4-5 They Make It, You Wear It Yes, the designer made a profit if he sold the suit for 260.00. If you add up all of the costs, the total cost comes to 238.00 (materials 128.00 + 16.00 + 6.00 + 40.00 + 8.00 198 sewing 40.00 198.00 + 40.00 238.00). If you subtract 238.00 from 260.00, the difference is 22.00. This is the profit the designer made. Answers will vary. The sketch should include basic geometric shapes.

Food and Drinks for the Show

Fashion designers sometimes provide refreshments at their fashion shows. They use their math skills to make sure that they purchase the right amounts. Suppose a designer is having a show, and 200 people will attend. He will serve bottled water and apples. Then he asks himself, How much should I buy He can use multiplication and division to find out. People attending a fashion show look carefully at the new designs and often make notes about which styles they like best.

Jackets by the Hour

The store owner wants all 100 jackets to be completed in one week. How many people must the designer hire to make them The designer knows it takes 4 hours to sew one jacket. A regular workday is 8 hours long. So one person can sew 2 jackets per day. There are 5 days in the workweek. So she multiplies the number of days by the number of jackets a person can make in one day One person can sew 10 jackets per week. But the designer needs to get 100 jackets made. She divides the total number of...

Runway Math

Planning fashion shows requires math skills. Sometimes a fashion show can be only a certain number of hours or minutes long. Designers must determine how many of their designs they can display at the show in that time. Sometimes designers know they want to display a certain number of designs. How long should the show be to allow all the designs to be seen Designers can use division or multiplication to figure out things like these. Suppose a fashion show will be 30 minutes long. Each model will...

By the Yard

Designers use math to make prototypes. The first thing they do is to determine how much fabric they'll need to buy. Fabric is often sold by the yard. This means that, often, you must buy a piece of fabric that is some whole number of yards long. If you buy 1 yard of fabric, for example, you are buying a piece that is 1 yard long. Since there are 3 feet in 1 yard, you can also say that 1 yard of fabric is 3 feet long. Most pieces of fabric are 4 feet wide. So a piece of fabric 3 feet (1 yard)...

How They Measure

Suppose a designer is making a prototype of a skirt. The skirt will be 33 inches long from This woman is using a measuring tape to measure the collar on a shirt. top to bottom. The designer decides she needs a piece of fabric 36 inches long. This gives her 1 extra inch of fabric to make the hem at the bottom and 2 extra inches to make the waistband. The waistband is a piece of fabric that goes around the waist. The designer places the end of her tape measure at the edge of her fabric. She runs...

Clothing and Geometry

Sketches may use circles or triangles. Some may use rectangles. For example, a designer may sketch a boy's jacket. He may use two rectangles to stand in for the sleeves and one for the main body of the jacket. There may be a hood shaped like a triangle. The designer can also use geometry in the design of the jacket. Maybe it will have square pockets on the front. A designer sketching a shirt must decide what size angle to use for the collar opening. Designers also use angles. Suppose a designer...

Symmetry Congruence and Beauty

Symmetry Fashion

Look at the sketch on this page for a woman's shirt. The front of the shirt has buttons going down the middle. On the left side of the buttons, there is a half-circle. You see the same half-circle on the right side of the buttons, except that it has been flipped over. The circle shape on the shirt has line symmetry. That means that one-half of the shape is the mirror image of the other half. Fashion designers often create clothes that have line symmetry. That's because many people think that...

Making the Prototype

Fashion Designer Prototype

A fashion designer works on a prototype of a dress design. A fashion designer works on a prototype of a dress design. rou know that designers think of an idea, make a sketch, and choose their fabric. Next, they make a prototype. A prototype is a sample of a design. It looks like the sketch, but it is made of fabric. This helps the designer see what the piece of clothing might really look like when it is completed. The designer may use the prototype to work on his design some more.

Using Congruent Shapes

Designers also use congruent figures in some of their designs. Congruent figures have the exact same shape and size. A circle and a square are not congruent. They do not have the same shape. A large square and a small square are not congruent. They do not have the same size. If two figures are congruent, when you place one over the other, the first one exactly covers the second. Congruent figures can make clothing interesting. Look at the skirt shown above. It has small triangles on it. The...

How You Tessellation Patterns

All of the figures fit together like a puzzle. There are no gaps between the figures. The figures do not overlap. Many mosaics are examples of tessellations because they are made up of tiles that are all the same size and all the same shape. There are different ways to make a tessellation. One way is called a slide. Study the tessellation on page 12. It is made from one figure that has four sides. Each figure in the farthest left row has been slid down and to...

Materials and Multiplication

But how much of each kind of fabric should she buy How much thread How many buttons The designer uses multiplication to find out. Here's how she does it. She knows that she needs 4 yards of denim for each jacket, and she knows that she needs to make 100 jackets So the designer needs 400 yards of denim. She needs 3 yard of nylon for the lining of each jacket So the designer needs 300 yards of nylon. She needs 1 spool of thread to sew each jacket So the designer needs 100 spools of thread. Each...

Making It Perfect with Fractions

A designer measures the length of a skirt. A designer measures the length of a skirt. When you see a beautiful dress or a cool shirt, do you think of fractions Probably not. But fractions and clothing go hand in hand. Fashion designers use fractions when they make clothes. Designers often have to add or subtract fractions. Sometimes a prototype looks too long after it is made. So the designer must cut off some fabric. How much fabric It depends on the measurement. Measurements often include...

Sewing and Selling

They use addition and subtraction to find out if they will make a profit on the clothes they make. The profit on a piece of clothing is the amount of money earned from selling it less all the costs of making it. For example, let's say a designer makes a dress. She buys the fabric for 50.00. The zipper costs her 5.00. She buys the thread for 3.00. She pays someone who works for her 30.00 to sew the dress. The designer uses addition to find out how much it...
