How to Make a Triangle Top for a Bathing Suit

Are you ready to create your own stylish triangle top for a bathing suit? In this article, we will guide you through the process step by step. From understanding the basic bodice block to choosing the right radius for the triangle top, we've got you covered. So let's dive in and make a trendy and comfortable triangle top that you can rock on the beach!

1. Introduction

Making your own bathing suit can be a fun and rewarding experience. Not only will you have a unique piece that fits you perfectly, but you'll also have the satisfaction of wearing something you created with your own hands. In this article, we'll focus on creating a triangle top for a bathing suit. This versatile and classic design is great for all body types and can be customized to suit your style preferences.

2. Understanding the Basic Bodice Block

Before we start creating the triangle top, it's essential to understand the basic bodice block. The bodice block is a foundation pattern used in garment making, and it serves as the starting point for creating different styles. By tracing a circle on the bodice block, we can create the base shape for the triangle top.

3. Choosing the Right Radius for the Triangle Top

To ensure a comfortable fit, it's important to choose the right radius for your triangle top. The radius determines the size and shape of the cups. For smaller cup sizes, a radius of 6.5 centimeters is recommended. If you have a medium cup size, opt for a radius of 7.5 centimeters. For larger cup sizes, a radius of 8.5 centimeters is suitable, while an extra-large cup size would require a radius of 9.5 centimeters.

4. Tracing the Circle for the Triangle Top

To begin the pattern, we will trace a circle using the chosen radius. Grab a piece of cardboard and trace a line with the radius of your circle. This will serve as a guide for creating the triangle top. Place the pattern hole in the middle of the circle and pivot the other side around to create a reference point for the middle. Then, trace a straight line from top to bottom on the circle.

5. Creating the Square Lines

Measure 1 centimeter from the top of the circle and 1.5 centimeters from the bottom. Trace a square line on both sides from the center line, starting from the bottom of the circle. Repeat this process twice, measuring 3 centimeters from the line on the bottom.

6. Connecting the Dots and Tracing the Triangle

Next, it's time to connect the dots and create the triangle shape. Trace a line from the 1 centimeter mark to the 3 centimeter mark on both sides. This will form the sides of the triangle. To ensure a better fit and more fabric to cover your bust, curve the lines slightly. Measure 1.7 centimeters from the middle of the line on both sides and use a curve to trace the bottom part of the triangle.

7. Curving the Lines for a Better Fit

To give the triangle top a more flattering shape, curve the lines slightly. Measure 1.7 centimeters from the middle of the line on both sides and use a curve to trace the bottom part of the triangle. This will provide extra fabric to cover your bust and create a better fit.

8. Adding a Hem for the Tunnel

To create a tunnel for the cord to attach under the bust, we need to add a hem to the bottom of the triangle top. Measure 1.5 centimeters parallel to the bottom line and trace another line. This will serve as the hemline and provide a clean and finished look to the triangle top.

9. Finishing the Sides of the Triangle Top

To complete the pattern, we need to finish the sides of the triangle top. Trace a square line from the bottom line, touching the 3 centimeter mark. This will ensure that the sides are secure and well-finished. Cut along the lines, but leave the bottom hemline intact, as it will be used as a tunnel.

10. Exploring Different Finishing Techniques

Now that the triangle top pattern is complete, you can explore different finishing techniques. One option is to use bias binding for a clean and professional finish. Another option is to use elastic and a fold to create a seamless and comfortable edge. You can also combine both methods, using binding on one side and elastic on the other to suit your style preference.

11. Options for the Lining of the Triangle Top

For added comfort and support, you may want to create a lining for your triangle top. This will not only enhance the durability of the garment but also provide a smooth and polished appearance. When creating the lining, make sure to trace two additional layers using the same pattern. We'll cover two options for the lining, including one with an opening for inserts.

12. Creating an Opening for Inserts in the Lining

If you want the option to insert shape pads or a push-up into your triangle top, you can create an opening in the lining. There are two ways to do this. The first method involves a straight line from the side to the bottom, with an extra centimeter for finishing. The second method uses a curved line along the contour of the side. Regardless of the method you choose, make sure the opening is secure and the finishing is neat.

13. Finishing the Opening in the Lining

To complete the lining, finish the opening using a suitable method. You can use a straight stitch, fold it, and zigzag to hold it down. Alternatively, you can use a narrow overlock stitch for a cleaner finish. Remember to leave a small opening that allows for easy insertion and removal of the pads or push-up.

14. Finalizing the Triangle Top Pattern

With the pattern complete, you can now proceed to cut the fabric and sew your triangle top. Follow the traced lines, ensuring accuracy and precision. Don't forget to leave seam allowances for the necessary finishing techniques. Once everything is sewn together, try on your triangle top and make any adjustments needed for the perfect fit.

That's it! You've successfully created a triangle top for your bathing suit. Enjoy wearing your custom-made garment at the beach or pool. Experiment with different fabrics, colors, and finishing techniques to make your triangle top truly unique. Have fun and happy sewing!
