The Measurement That Ruins Everything
You try on a beautiful top or dress. It looks great standing still. Then you raise your arm to reach for something and suddenly it feels like the garment is attacking you.
Welcome to the world of armhole depth — the silent killer of plus-size fit.
Hi, I’m Tessa Brenner, former Torrid buyer and the woman who once argued with a factory for two extra inches of armhole (and won). Today in The Pattern Room we’re going deep on the one measurement that affects comfort more than almost anything else.
The body’s not the problem. The pattern is.
What Armhole Depth Actually Is
Armhole depth refers to how low the armhole opening sits under your arm. It’s not just about width — it’s about the vertical drop from shoulder to underarm.
A shallow armhole cuts into your armpit and restricts movement. A properly deep armhole allows you to move freely while still looking polished and put-together.
In smaller sizes, a higher armhole often works fine. In plus sizes, it becomes a disaster because bust, back, and upper arm measurements are larger.
Why This Matters So Much for Plus-Size Bodies
As sizes increase, the relationship between shoulders, bust, and arms changes. A good pattern adjusts the armhole curve to accommodate this. Many brands don’t.
Consequences of shallow armholes:
Restricted arm movement
Fabric bunching and digging under the arms
Visible bra lines or side spillage
The garment riding up when you move
General discomfort that makes you want to change immediately
I’ve seen women reject perfectly nice garments simply because the armholes made them miserable.
The Factory Story That Still Makes Me Laugh
During one particularly memorable buying trip, I refused to approve samples until the armholes were fixed. The factory manager kept saying “But it looks fine on the model!”
The model was a size 14. We were sampling up to size 30.
I literally drew on the sample with tailor’s chalk to show where the armhole needed to drop. Two weeks later, the revised samples came back dramatically better. Sales numbers proved I was right.
How to Check Armhole Depth in the Fitting Room
Next time you try something on, do this quick test:
Put the garment on properly.
Stand naturally, then raise both arms straight overhead.
Lower them and reach forward as if typing or driving.
Raise arms out to the sides like a T.
If you feel pulling, restriction, or the need to adjust constantly — the armholes are too shallow.
Pro tip: Look in a three-way mirror while moving. The armhole seam should sit smoothly against your body without cutting in.
Technical Details Most Shoppers Never Learn
In proper pattern grading, armhole depth should increase with size. The curve should also change shape to accommodate bust projection and upper arm circumference.
Common mistakes brands make:
Simply enlarging the armhole circle without dropping it
Keeping the same armhole shape across all sizes
Prioritizing “sleek look” over actual wearability
The best brands treat armhole depth as a science, not an afterthought.
Brands Getting Armholes Right
From my experience and client feedback:
Some Eloquii styles show real attention to this
Universal Standard tends to do better
Certain independent designers prioritize movement
I always test armholes thoroughly before recommending anything to clients.
Building the Habit of Checking First
Train yourself to check armholes before looking at color, price, or trendiness. It will save you so many returns and closet regrets.
My husband (well, wife Laura) teases me because I reach for the shoulder and armhole area first in every store. She’s not wrong — it’s become automatic after years of training.
Even my daughter Nia has started mimicking me when we shop for her clothes. “Armhole check, Mama!”
The Freedom That Comes With Good Armholes
When you wear something with proper armhole depth, you forget you’re wearing it. You can move, gesture, work, hug, and live without constant adjustments.
That freedom is what I want for every reader here.
Stop accepting discomfort as normal. Start demanding better construction. Your clothes should work with your body, not against it.
Next Steps in The Pattern Room
We’ll continue exploring the technical side of fit — shoulder-to-bust ratios, proper grading, and more tools to help you shop smarter.
In the meantime, I challenge you to try on your next garment with armhole awareness. You’ll be amazed at how much it changes your shopping experience.
Your comfort and confidence are worth the extra attention to detail.
Now go raise those arms with confidence.
