My Buying Guide on ‘Onesies Patterns Sewing For Adults’

I have always loved wearing onesies, they are comfortable, cozy and perfect for lounging around at home. However, finding onesies in adult sizes can be a challenge, and even when I do find them, the patterns are limited. That’s when I decided to learn how to sew my own onesies using patterns specifically designed for adults. If you are also looking to make your own onesies, here is my buying guide on ‘Onesies Patterns Sewing For Adults’.

1. Determine Your Size

The first step in choosing the right onesie pattern is to determine your size. Unlike ready-made onesies, sewing patterns come in different sizes, so it is crucial to know your measurements before purchasing a pattern. You can take your measurements yourself or ask someone to help you.

2. Consider the Style

Next, consider the style of onesie you want to sew. Do you prefer a classic full-length onesie or a short romper style? There are also options for hooded or non-hooded styles, with or without pockets, and different types of closures like zippers or buttons. Think about what style will be most comfortable for you.

3. Check the Skill Level

When browsing through different patterns, make sure to check the skill level required for each one. If you are new to sewing or just starting out with making garments, choose a pattern that is labeled as ‘beginner’ or ‘easy’. As you gain more experience and skills, you can move on to more complex patterns.

4. Look at Fabric Requirements

Each pattern will have a list of fabric requirements, including the type of fabric needed and the amount in yards/meters. Make sure to check this before purchasing as it will affect the overall cost of your project.

5. Read Reviews

Before making a purchase, take some time to read reviews from others who have used the same pattern. This will give you an idea of any potential issues with sizing or instructions.

6. Consider Additional Supplies

Apart from fabric and thread, some patterns may require additional supplies like elastic bands or interfacing materials. Make sure to check if these supplies are included in the pattern or if you need to purchase them separately.

7. Check for Multiple Sizes

Some patterns may come with multiple sizes included in one package while others may require you to purchase each size separately. If you plan on making multiple sizes or want room for adjustments later on, opt for a pattern that includes all sizes.

8. Choose a Reputable Brand

Lastly, choose a reputable brand when purchasing your onesie pattern. This ensures that the instructions will be clear and easy to follow and that the sizing will be accurate.

With these tips in mind, I hope you can find the perfect onesie pattern for your next sewing project! Happy sewing!
