Learn how to check clothing quality by examining seams, stitches, and stress points. A practical quality stitching guide for buying durable clothing that lasts.
Quick answer
To spot quality stitching, turn the garment inside out and check four things: tight, even stitches; reinforced stress points; flat seams that do not twist; and clean thread tails. If the inside looks as tidy as the outside, the garment is likely well made. Prioritise these checks over brand names or price tags.
You do not need to be a tailor to judge clothing construction. A few minutes of close inspection can tell you whether a garment will survive regular wear or fall apart after a handful of washes. The inside of a garment often reveals more than the outside.
This guide walks you through a practical sequence for checking stitching quality. Each step includes a common mistake to avoid and a checkpoint to confirm what you are seeing. Use it next time you shop, whether in person or when your order arrives.
Why stitching matters more than fabric alone
A beautiful fabric can be undone by poor stitching. Seams that are loose, uneven, or poorly finished will pull apart at the first sign of stress. Good stitching distributes tension evenly, so the garment moves with you instead of tearing. It also keeps shape after washing, which is why well-made clothing often looks better for longer.
When you check clothing quality, start with the seams. They are the skeleton of the garment. If the seams are strong and flat, the rest of the construction is likely to be sound. If they pucker, twist, or have long thread tails, treat that as a warning sign.
- Look for stitch density: more stitches per inch generally means a stronger seam.
- Check that seam allowances are finished, not raw and fraying.
Step-by-step: how to inspect stitching
Turn the garment inside out. Run your fingers along the main seams. You are feeling for bumps, loose threads, and skipped stitches. A quality seam feels smooth and consistent. Next, gently pull the seam apart. It should not gape or crackle. If it does, the stitching is too loose or the thread is weak.
Then check the stress points: underarm seams, crotch seams, pocket corners, and where straps attach. These areas should have reinforced stitching, often a double row or a bar tack. Finally, look at the hem. A good hem is straight, with no twisting, and the stitches are barely visible from the outside.
- Common mistake: only looking at the outside. The inside tells the real story.
- Checkpoint: if you see loose threads longer than a few centimetres, be cautious.
What good stitching looks like on specific garments
On underwear and crops, the seams should be flat or flatlock to avoid chafing. The Longline Crop Scratchy features a double layer at the front and a flatter seam at the bottom, which is a good example of construction designed for comfort and support. This double layer also adds compression for smaller busts and more room for bigger busts.

For men's boxers, the Pouch Boxer Banana has a double-layered pouched area that acts as a gusset. That kind of construction requires precise stitching to keep the pouch shape without twisting. When you inspect a boxer, check that the pouch seam is smooth and that the waistband is securely attached with even stitching.

- Flat seams reduce bulk and irritation, especially in activewear and underwear.
- Reinforced bar tacks at pocket corners and fly openings are a sign of durability.
Your 5-step stitching check
- 1. Turn it inside out: Inspect the interior seams first. Look for loose threads, skipped stitches, and unfinished edges. Checkpoint: if the inside looks messy, the outside will eventually suffer.
- 2. Test the main seams: Gently pull a main seam apart. It should not gape or make a cracking sound. Run your finger along it to feel for bumps. Common mistake: pulling too hard and damaging the garment. Use gentle tension.
- 3. Check stress points: Examine underarms, crotch, pocket corners, and strap attachments. These should have reinforced stitching or bar tacks. If stress points are not reinforced, expect early failure.
- 4. Look at the hem: A good hem is straight and lies flat. Stitches should be even and not visible from the outside. Twisted or wavy hems are a sign of poor cutting or stitching.
- 5. Compare inside and outside: The outside may look perfect, but the inside reveals true quality. If both are tidy, you have found a well-made garment. Use this check before buying or before removing tags.
Construction details that show quality
- Longline Crop Scratchy: Features a double layer at the front, flatter seam at the bottom and more room for bigger busts than the Original Crop Top. A flatter seam reduces chafing, while the double layer adds support and compression where needed. This shows thoughtful construction for comfort.
- Pouch Boxer Banana: The Pouch Boxer has a double layered pouched area providing extra room in the front. Because it is double layered it does act as a gusset. A double-layered pouch requires precise stitching to maintain shape and comfort. It is a practical example of how construction affects fit.
- Sky Rise Plain Black: An extra high waisted version of our originals. They are a very comfortable full brief that sit high on your natural waist and taper in at the top, so stay right where they are meant to all day long. The tapered waistband relies on strong, even stitching to stay put without digging in. This is a sign of quality you can feel.
Quality stitching is not about perfection on the surface; it is about consistency and reinforcement where it counts. Next time you shop, take a moment to turn the garment inside out and run through these steps. Your clothes will last longer, and you will get more value from every wear.
