Inside a Garment: What to Look at Before You Buy

Most people judge clothing from the outside. The outside is designed to sell. The inside tells you whether it's worth buying.

Picking up a garment in a store, the first thing most people do is look at the front. The color, the silhouette, how it photographs in their head. Then maybe the price tag.

Almost nobody turns it inside out.

That's a problem, because the outside of a garment is marketing. It's been pressed, styled, and lit to look as good as possible. The inside is construction. It's where the brand can't hide anything, because nobody was supposed to look there.

Learning to read the inside of a garment takes about ten minutes of practice. After that, you'll never evaluate clothing the same way again.

Here's exactly what to look for.

The Seams

Seams are the skeleton of a garment. Everything else rests on them. If the seams are poor, nothing else matters.

Seam type is the first thing to check.

The most common seam finish in mass production is the overlock, sometimes called a serged seam. You'll recognize it immediately: a zigzag or looped thread running along the raw edge of the fabric. It's fast, cheap, and functional. It prevents fraying, which is its only job. It does nothing for longevity or appearance. Most mid-range and fast fashion garments use overlocked seams throughout.

A French seam is something different entirely. Instead of leaving raw edges and finishing them, a French seam folds the raw edges inside itself, enclosing them completely. There is no exposed thread, no raw fabric, nothing that can fray or catch. When you look at a French seam, you see a clean fold of fabric. Nothing else. This seam type requires significantly more skill and time to execute. It's the standard in quality lingerie, silk garments, and fine tailoring. If a brand uses French seams, they're not cutting corners on construction.

A flat-felled seam goes even further. You see it most often in denim and high-quality shirts: two parallel rows of stitching on the outside with a clean, flat join on the inside. It's one of the strongest seam constructions possible and indicates serious attention to durability.

Seam allowance is the second thing to check.

After you identify the seam type, look at how much fabric is left beyond the stitch line. This is the seam allowance, and it matters more than most people realize.

A generous seam allowance, typically 1.5cm or more, tells you two things. First, the brand accounted for the reality that bodies are not identical and alterations may be needed. A skilled tailor can take a garment with proper seam allowance and adjust it meaningfully. Second, it tells you the garment was made with some intention of longevity. Tight seams under stress eventually pull apart. Wide seam allowances absorb that tension.

A narrow seam allowance, often seen in fast fashion, means the garment cannot be altered without risking the seam itself. It also means the brand didn't expect you to keep it long enough to need alterations.

Seam pressing is the third thing to check.

Open any quality tailored piece and look at the seams. They should be pressed flat and open, each side lying cleanly away from the center. Unpressed seams create bulk, distort the fabric's hang, and indicate that finishing steps were skipped.

Run your finger along the seam line. If you feel a ridge or the seam rolls to one side, the pressing was inadequate. If it lies flat and clean, someone took the time to do it correctly.

The Lining

Not every garment needs a lining. A linen shirt doesn't need one. A summer dress often doesn't. But for tailored pieces, structured garments, wool coats, and anything where the outer fabric would be uncomfortable directly against skin, the lining is essential. And it tells you an enormous amount about how the garment was made.

Lining fabric is the first indicator.

Polyester lining is the default in most garments. It's cheap, it doesn't wrinkle badly, and it's easy to work with. It's also hot, not particularly pleasant against skin, and doesn't breathe. A garment lined in polyester is not a garment someone spent money finishing.

Cupro lining is meaningfully better. It's a semi-synthetic fiber made from cotton waste, breathes well, drapes beautifully, and feels close to silk against skin. It's used by brands that care about the wearing experience, not just the production cost.

Silk lining is the best. It's cool against skin, extraordinarily smooth, temperature-regulating, and durable when properly maintained. It also adds weight and drape to the outer fabric in a way no synthetic can replicate. A cashmere coat with a silk lining moves and hangs differently than the same coat lined in polyester. Better, always.

If a brand uses silk lining in tailored pieces, they've made a significant cost decision in favor of quality. It's one of the clearest signals available.

How the lining is attached matters as much as what it's made from.

A properly attached lining has ease built into it. This means the lining is slightly larger than the garment's interior, allowing the outer fabric and lining to move somewhat independently. When you raise your arms or sit down, the lining moves with you rather than pulling against the outer fabric. A lining cut too tight will pull at seams, pucker at stress points, and eventually tear.

Look at the hem of a lined garment. The lining should be attached in a way that allows independent movement, either with a jump hem (the lining hangs slightly shorter than the outer fabric and moves freely) or with a hand-stitched connection that allows flexibility. A lining machine-stitched directly to the hem with no ease is going to create problems with repeated wear.

Lining coverage tells you about priorities.

In cheaper garments, you'll sometimes see partial lining: the bodice is lined but the sleeves aren't, or only the front panels are lined. This saves material and labor. In quality garments, the lining covers the full interior, including sleeves in coats and jackets. Unlined sleeves in a lined coat are a compromise, not a design choice.

The Finishing

If seams are the skeleton and lining is the interior, finishing is everything that determines how long the garment holds together and how it looks after repeated wear. This is where shortcuts are easiest to take and hardest to see.

Hems are the most telling finishing detail.

Turn up the hem and look at how it's done.

A machine-stitched hem is the fastest option. One visible line of stitching on the outside, the raw edge usually overlocked above it. It's functional, it holds, and it announces itself. You can see the stitch line on the outside of the garment.

A blind hem is done by machine but uses a special stitch designed to be nearly invisible from the outside. It's better than a standard machine hem and is the minimum standard for quality ready-to-wear.

A hand-stitched hem is the best. Small, even stitches done by hand, invisible from the outside, barely visible from the inside. No single stitch carries enough tension to create a ridge or pull. The hem lies flat and moves naturally with the fabric. This takes significant time, which is exactly why most brands don't do it. When you find it, you're holding something made by someone who knew what they were doing and was given the time to do it.

Buttonholes reveal construction quality immediately.

Cheap buttonholes are machine-cut and machine-stitched in seconds. The thread is often thin, the edges pull with repeated use, and within a year the buttonhole starts to fray and open.

Hand-worked buttonholes are done with a needle and thread, stitch by stitch, with the fabric cut after the stitching is complete (not before, which risks fraying). The thread is dense and tight. The edges are finished with a bar tack at each end. They will not fray. Ever. They look different from machine buttonholes once you know what to look for: rounder, more dense, slightly raised, completely even.

If you're looking at a coat or jacket, run your finger across the buttonholes. Hand-worked buttonholes have a distinct texture. Machine buttonholes feel thin and almost fragile by comparison.

Edge finishing on facings and interior pieces matters.

Facings are the fabric pieces that finish necklines, front openings, and armholes on the interior of a garment. In quality construction, these are understated and clean, lying flat against the interior without rolling or bubbling.

Look at how the facing edge is finished. In cheap garments, it's often just overlocked and left. In quality garments, it's either turned under and stitched, or finished with a strip of fabric (Hong Kong finish) that encases the raw edge completely. Both take more time. Both result in a cleaner interior that holds its shape over years of wear.

Bartacks at stress points.

These are small, dense clusters of stitching reinforcing the points where the garment experiences the most tension: the base of pocket openings, the top of a pleat, the end of a fly opening. You'll recognize them as a small rectangle or oval of tight thread.

Their presence or absence tells you whether the brand thought about how the garment would actually be worn. A pocket opening without a bartack will eventually tear. With one, it won't. This is a detail that takes seconds to add and costs almost nothing. Brands that skip it simply didn't care enough to include it.

What You're Actually Looking For

You don't need to memorize all of this for every purchase. Narrow it down to three questions you can answer in sixty seconds:

How are the seams finished? Overlocked only, or something better. If it's French seams, that's significant. If it's just overlock, acceptable for the price point but not a quality indicator.

What is the lining made from? Touch it and ask whether it feels like something you'd want against your skin. Silk or cupro versus polyester is a real difference you can feel immediately.

Look at one hem and one buttonhole. These two details tell you more about how the garment was made than almost anything else visible. If the hem is hand-stitched and the buttonholes are dense and clean, everything else is probably done well too.

The outside of a garment is designed to make you want it. The inside tells you whether it will still be worth wearing in ten years.

Turn it inside out before you decide.
