Collars and sleeves are the first things you touch when you pick up a basketball jersey, and they are also the part that decides whether the shirt hangs cleanly or pulls across the chest. Two variables do most of that work: the shape of the collar around your neck, and the way the sleeve is joined at the shoulder. Once you can name what you are looking at, a product photograph becomes readable, because a V-neck versus a crew neck and a set-in versus a raglan shoulder each tell you something different about fit, drape and durability. Small construction changes are what change everything, and this guide breaks down the collar shapes you will actually find on basketball jerseys, the sleeve constructions behind the shoulder line, and the measurements that make the difference legible.
Four necklines cover almost every basketball jersey
Basketball jerseys use a narrower slice of neckline vocabulary than general apparel, and once you know the four families you can place almost any design immediately. The close round neck sits at the base of the neck and is finished with a rib band; the V-neck drops to a point at centre front and is the modern default in basketball; the mock neck is a short standing band that rises partway up the neck without folding; and the scoop is a wider, deeper curve used mainly on women's cuts and a small number of men's styles. Henley and polo openings exist but are vanishingly rare on basketball jerseys, because both need a placket and extra hardware that a game jersey has no use for.
Men's cuts are usually drafted higher and narrower than women's, and men's V-necks are normally shallower. That is a grading convention rather than a rule about your body, and it is the reason the same nominal size can feel higher at the neck in one range than in another.
Three measurements that settle every argument about fit
A neckline is specified with three measurements rather than a name, and those three are what actually decide whether a collar works. Front neck drop is the distance from the high point of the shoulder down to where the neckline ends at centre front. Back neck drop is the same measurement at centre back, and it is the one most often left vague, which is why back necklines drift between samples. Finished opening is the total circumference of the neckline once it is sewn, and it is the number that decides whether the garment can be pulled over the head at all.
The finished opening interacts with the fabric in a way that catches people out. A stretch rib can extend by roughly 40 to 50 percent of its own length, so a knitted opening can be noticeably smaller than a head and still pull on comfortably. An opening measured at 15 or 16 inches in the flat therefore stretches to somewhere in the region of 21 to 24 inches, which is enough to clear an adult head. A woven fabric gives nothing, so the same opening would have to be as large as the head, or the garment would need a placket, a keyhole or a zip. The same crew neck is a different pattern in a knit than in a poplin, and only one of them works as a closed pull-on.
Set-in and raglan are two different answers to the same problem
Everything above the chest is decided by how the sleeve meets the body. In a set-in sleeve the sleeve is a separate piece sewn into an oval armhole, and the seam passes over the high point of the shoulder and encircles the arm. Because the cap of the sleeve is curved and slightly larger than the opening it joins, a small amount of extra material, usually something in the order of half an inch to an inch and a half, is eased in so the sleeve sits over the shoulder without puckering. That amount is called cap ease, and it is the quiet number that decides whether the sleeve hangs straight or bulges.
Ease at the low end produces diagonal wrinkles running toward the cap, which means the sleeve is short over the shoulder. Ease at the high end produces visible fullness and a puffed look at the shoulder, which reads as more relaxed but less tidy. Raising the cap and deepening the armhole together moves the garment toward the tailored end of the spectrum, giving a cleaner hang with the arm at rest and costing some freedom of movement when the arm is raised. Basketball jerseys sit at the roomy end of that trade-off by design.
The raglan takes a completely different route. The sleeve is cut in one piece with the body, so the seam runs diagonally from the neckline to the underarm and no seam sits on the shoulder bone at all. Because the shaping is distributed along that long diagonal instead of being concentrated in a rounded cap, the fabric moves with the body rather than pivoting around one small point. The construction takes its name from FitzRoy Somerset, 1st Baron Raglan, who lost his right arm at Waterloo in 1815 and asked for a coat that would let him fight and ride with the arm he had left; the pattern was developed for him by John Emary of the London tailoring firm Aquascutum during the 1850s and was in general English use by around 1862. It reached American sport through baseball, where a raglan mid-length sleeve became the standard undershirt under the jersey for exactly the reason the military coat wanted it: the shoulder stays free.
What a product photograph can and cannot tell you
A photograph cannot tell you cap ease, rib recovery or how the pattern was graded, because those are decisions inside the garment rather than on its surface. What it can tell you is the shape family, the seam path and roughly how the collar is finished. Those three narrow the field enough that a size chart and a fabric description finish the job.
- 1Check the shoulder before the chest. The seam path tells you more about how the jersey will move than the chest measurement on the size chart does.
- 2Look at the collar edge in raking light. A flat, shadowless edge means the band was fitted under tension. A rippled edge means it was not.
- 3Treat a wide V on a large size as a grading flag. Depth should grow in planned increments, not in proportion to chest width.
- 4Read the collar, then read the size. When two sizes both fit your chest, the neckline usually decides between them.

The other pages that describe what surrounds the neckline
Start with the full basketball jersey index to see every construction side by side, then read how basketball jerseys are actually made for the decoration side of the same garment. For sizing the fit this collar has to work with, our youth and kids sizing guide and adult sizing guide cover the measurement side; for the builds where the decoration sets the limit on how the neckline can be pressed, see the guide to reading the care symbols.
The useful habit is to read a jersey the way you would read a pattern. Shape the outline, name the seam paths, then judge the measurements that follow from them. A collar that lies flat and a sleeve that hangs straight are the two results worth checking on any jersey you own, because everything else on the shirt can be changed by choosing a different era while those two cannot.
Frequently Asked Questions
Five questions that come up when people start reading construction instead of just reading the size chart.
Q1What is the difference between a set-in sleeve and a raglan sleeve on a jersey?
A set-in sleeve is a separate piece sewn into an oval armhole, so the seam runs over the top of the shoulder and all the way around the arm, and a small amount of extra cap material is eased in so the sleeve sits smoothly on the rounded shoulder. A raglan sleeve is cut as one piece with the body, so the seam travels diagonally from the neckline down to the underarm and there is no seam sitting on the shoulder bone at all. That diagonal lets the fabric move with the body instead of pivoting around a single shoulder point, which is why raglan construction became standard on baseball undershirts.
Q2Why does the collar of some basketball jerseys go wavy after washing?
A wavy or rippled collar is a fitting problem rather than a fabric problem. The neck band is normally a stretch rib cut slightly shorter than the neckline it joins, so it is stretched as it is sewn on and that tension is what makes it lie flat. Cut the band too long, or use a rib with too little recovery, and the excess length has nowhere to go once the garment is washed and relaxed. A body fabric and a collar rib that shrink at different rates produces the same result, which is why the fit can change even on a jersey you only washed once.
Q3Is a V-neck jersey supposed to be deeper on larger sizes?
Yes, and this is a grading decision rather than a defect. A neckline does not scale by the same rule as chest width or body length, so factories add depth deliberately as the size goes up, commonly in increments of around a fifth of an inch per size, to keep the proportion stable. The reason a poorly graded V-neck can drift toward a wide boat shape on a large size is that the depth was left to be derived from the chest measurement alone, which makes the opening grow far faster than the neck it is supposed to sit on.
Q4Does the collar style affect which size I should order?
It can, because neckline comfort is not the same as body size. A deep V exposes more of the chest and reads more forgiving than its measurements suggest, while a shallow crew sits closer to the collarbone and makes the wearer think about the neck opening first. When you are between two sizes, the collar is usually the better tiebreaker, because the chest measurement already tells you what the body circumference is doing.
Q5How can I tell a raglan sleeve from a set-in sleeve in a product photo?
Look at the top of the shoulder rather than the sleeve length, because length tells you nothing. On a set-in sleeve there is a seam running across the shoulder from the neck to the outside of the arm. On a raglan the fabric arrives at the collar in one piece, so what you see is a diagonal line starting near the neck and running down toward the underarm, and often a colour break along that same diagonal. Contrast panels make the diagonal obvious; matching panels make it subtle but still visible at the collar.
