The overlock seam in clothing and what it says about the finish
Short answer: The overlock seam is the stitched edge where fabric is joined and the raw edge is bound in. It can say something about how a garment is sewn, but it does not decide quality on its own. Here is what to look for when you turn a vest or a pair of underpants inside out.
What an overlock seam is
An overlock seam joins two pieces of fabric and binds in the edge at the same time, so the fabric does not fray. You can see it as a row of dense threads along the edge, often on the inside of a shirt or trousers. It is used especially on knitted and stretchy fabric, because the seam gives a little when you move.
What a neat seam looks like
A neat overlock seam is even and dense, with no loose threads, and lies flat against the fabric. Look for even stitches and an edge that does not ripple or pull. For something to compare with, look at bamboo underwear for men and turn a few garments inside out to see the seams.
Where a seam can bother you
A hard, thick seam can rub against the skin, especially at the neck, arm and waistband. Many people therefore choose garments where the seam lies flat or is covered. Feel it with your fingers and try the garment on, so you notice whether the seam presses when you move or sit.
Loose threads and what they mean
A single loose thread is often harmless and can be snipped off, as long as you do not pull it. Many loose threads along a seam may suggest that the seam is not quite finished. Cut the thread close to the fabric with small scissors and avoid tearing it, so the seam does not come undone.
Seam and elastic work together
At a waistband or edge the seam often sits together with an elastic that has to follow the body. If the seam is tight and stiff, it can work against the elastic, and the waistband becomes uncomfortable. Put a finger inside and stretch a little to see whether the seam gives with it.
Why the seam matters for durability
The seam holds the garment together, and if it is poor the garment can come apart even though the fabric is intact. That makes the seam one of the places to check before you buy. A well-sewn seam can last through many washes, but you only see the whole picture over time.
Washing and the seam
Wash clothes by the label and turn them inside out so the seams take the least rubbing. Avoid high heat, which can tighten the thread and pull the fabric together along the seam. Lay the garment flat or hang it up so the seam is not pulled out of line by the weight of wet fabric.
The seam is only part of the picture
A good seam is a good sign, but fabric, fit and washing also decide how long clothes last. Look at bamboo underpants for men and bamboo T-shirts for men and compare several things before you decide. Feel, look and try on, and let your own experience be the measure.

What is an overlock seam?
It is a seam that joins two pieces of fabric and binds in the edge at the same time, so the fabric does not fray. It is often used on knitted and stretchy fabric because it gives a little when you move.
Is an overlock seam a sign of good quality?
It can say something about how a garment is sewn, but it does not decide quality on its own. Fabric, fit and washing matter too, so look at the whole garment and try it on.
May I cut off a loose thread?
Yes, a single loose thread can be snipped off close to the fabric with small scissors. Do not pull it, since the seam can come undone. Many loose threads along a seam deserve your attention.
