Adjust your sewing patterns confidently using simple sewing tools and techniques to create garments that fit and flatter your body shape.

A companion to "How to Choose the Best Sewing Pattern for You"

You’ve chosen the perfect sewing pattern — it’s time to make it fit you perfectly. Whether you’re sewing a blouse, a dress, or a pair of pants, learning how to make minor adjustments to your pattern will help you sew clothes that look great and feel just right. In this guide, you’ll learn how to confidently adjust a sewing pattern for the perfect fit so you can wear your handmade garments with ease, style, and pride. 

Half the job of sewing a garment is adjusting and cutting the sewing pattern. This is the first step to sewing a perfect garment. Once you have made the pattern adjustments and cut the sewing pattern, the rest of your sewing project will be a breeze. 

Why Pattern Adjustments Matter

Most commercial sewing patterns are based on standard body measurements, but real bodies are beautifully unique. Pattern adjustments allow you to:

Improve comfort and movement

Flatter your specific body shape

Fix common fit issues (like gaping necklines or tight arms)

Turn a “close fit” into a “custom fit”

Understand Your Body’s Measurements

Before you adjust a pattern, you need accurate body measurements. Key measurements to take include:

Full bust

Waist

Hips

Back waist length

Shoulder width

Upper arm circumference

Use a flexible measuring tape and write everything down. Keeping a sewing journal with measurements is important for all your sewing projects. Also, keep notes on adjusting, cutting, and sewing your pattern in case you need to make adjustments or do not want to forget fine details that made your garment perfect.

Compare your numbers to the pattern’s size chart, and note where your measurements differ in your sewing journal.

✂️Basic Tools You’ll Need

Pattern paper or tracing paper

French curve or hip curve ruler

Measuring tape

Pencil and clear ruler

Scissors

Tape or pins (Pins can be used to stay your adjustments on pattern pieces instead of tape. You can reuse your pattern pieces and make new adjustments with pins. Once you use tape on paper pattern pieces, you cannot undo the adjustments using tape.)

Optional: dress form or muslin for testing

Standard Pattern Adjustments (And When to Use Them)

➤ Full Bust Adjustment (FBA)

This is perfect if your bust measurement is larger than the pattern size. It adds fullness and prevents pulling or gaping.

➤ Small Bust Adjustment (SBA)

For those who find too much ease in the bust area, this removes excess fabric while maintaining shape.

➤ Length Adjustments

Add or subtract length at the waist, hem, sleeve, or bodice to match your torso, arms, or legs. If you are petite or tall, adjusting your sewing pattern for length is critical. 

➤ Widen or Narrow the Hip

Adjust pants, skirts, or dresses to improve the fit at the hips using the slash-and-spread method or pivoting technique.

➤ Adjusting for Swayback

If you see pooling or bunching in the lower back, removing the length of the back waistline can fix it.

➤ Full Bicep Adjustment

Adds room to sleeves for a more comfortable fit in the upper arms.

How to Make the Adjustments Step-by-Step

1. Trace your original pattern onto a separate sheet of tracing paper, pellon, or pattern paper. 

2. Mark key adjustment lines (many patterns include these).

3. Slash, spread, or overlap as needed — use rulers to keep edges smooth.

4. Redraw seam lines using a French curve.

5. Add seam allowances if any were lost during cutting.

6. Label your changes for easy reference later.

Test the Fit First

Always make a muslin or toile before cutting your final fabric:

Use inexpensive cotton or a similar-weight fabric.

Sew with long basting stitches.

Try it on and mark any new fit changes.

This step saves you time, frustration, and fabric! (Make notes in your sewing journal of your sewing process for each sewing project.)

Making pattern adjustments may seem intimidating initially, but like all sewing skills, it gets easier the more you practice. And once you learn to tailor a pattern to your shape, you’ll wonder how you ever sewed without it!

You deserve garments that fit and flatter — and adjusting your patterns gives you that power. ✨

How To Choose The Best Sewing Pattern For You

By choosing sewing patterns that suit your body shape, you ensure your sewing creations will be worn and loved. 

How to Choose the Best Sewing Pattern for Your Body Shape, Style, and Comfort

Have you ever stood in front of your closet, full of clothes, yet felt like you had nothing to wear? You're not alone. Often, the problem isn't the clothes but how they fit, feel, or reflect who we are. Also, they do not mix and match with the rest of your clothes, which can be limiting. 

When you sew your wardrobe, you have a rare opportunity: to create clothes that flatter your body, match your style, and feel as good as they look. But it all starts with choosing the correct sewing pattern.

👗 Know Your Body Shape

Understanding your body shape is the first step in selecting a pattern you'll love wearing. Here are a few common shapes and styles that tend to work well for each:

Hourglass: Balanced bust and hips with a defined waist. Try fitted dresses, wrap styles, and skirts that emphasize the waist.

Pear: The hips are wider than the bust. A-line skirts, structured tops, and boat necklines balance proportions.

Apple: Fuller midsection with slimmer legs. Empire waists, flowy tops, and V-necks create a flattering silhouette.

Rectangle: Bust, waist, and hips are similar in width. Look for belted styles, peplums, or garments that add curves.

Inverted Triangle: Broad shoulders with narrower hips. A-line skirts and scoop necklines help balance the frame.

You don’t need to box yourself in, but choosing patterns that suit your shape gives you a strong start.

🕊️ Choose Timeless, Classic Patterns

Fads fade. But classics? They stay. Fashion never goes out of style either. 

When choosing a sewing pattern, opt for silhouettes that have stood the test of time — think A-line skirts, sheath dresses, button-up shirts, and well-cut trousers. These pieces can be styled differently across seasons and years, ensuring they aren’t forgotten in your closet.

A classic pattern is like a canvas — you can sew it repeatedly, changing fabric, sleeves, or length to give it a fresh twist every time.

Classic sewing patterns save money because you don't have to rebuy sewing patterns over and over. Classics are timeless and never go out of style. You can always restyle the same classic sewing pattern. 

☁️ Prioritize Comfort & Fit

If it’s not comfortable, you won’t wear it. It’s as simple as that.

Look at the pattern’s ease — does it allow enough room to move?

Consider fabric recommendations. The wrong fabric can turn a great pattern into an uncomfortable piece.

Adjust for your personal fit preferences — lengthen hems, tweak waistlines, and don’t be afraid to blend sizes.

You deserve clothes that move with you, not against you.

🎨 Style It Your Way

Just because a sewing pattern is classic doesn’t mean it has to be boring.

Use color, fabric texture, buttons, and trims to reflect your unique style. You can make the same dress look modern, vintage, boho, or romantic depending on your details.

Love bold prints? Go for it. Prefer neutrals? Make them luxe. Your sewing should feel personal.

✂️ Final Thoughts

The best sewing pattern suits your body, life, and style while feeling great to wear.

Because the goal isn’t just to sew pretty clothes, it’s to sew clothes that you’ll live in — confidently, comfortably, and joyfully. In other words, sew clothes that are comfortably stylish and functional.
