Where does the sleeve join the shoulder?
The most useful thing about a sleeve is not the sleeve. It is where the sleeve meets the body, because that seam decides how the entire garment sits, and the sleeve itself only affects the arm.
Two knits with identical sleeves, one with a shoulder seam on the shoulder and one with it halfway down the upper arm, look like different garments from across a room. Shops know this and put the shoulder construction in the title, which means it is worth reading first.
- Set-in. A seam running in a circle around the shoulder joint, ending where your shoulder ends. Structured, and the standard on shirts and tailoring.
- Raglan. One piece from the underarm to the neckline, with a diagonal seam travelling from the armpit towards the collar. No shoulder point at all.
- Drop shoulder. The seam sits below the natural shoulder, partway down the upper arm. Reads as oversized instantly.
- Dolman. No shoulder seam. The sleeve is cut as part of the body, wide at the armhole and narrowing to the wrist.
- Batwing. Dolman taken further, with a deep underarm that opens into a wing of fabric when the arm lifts.
- Saddle. A raglan variant where the sleeve extends across the top of the shoulder in a strip, common on knitwear.
In a photo, look at where the seam crosses the arm. On the shoulder bone is set-in. Below it is drop shoulder. Running diagonally to the neck is raglan. No seam at all is dolman.
What are the sleeve lengths called?
Sleeve length has more named steps than most people expect, and two of them sit close together.
- Sleeveless. No sleeve, with the armhole finished.
- Cap. A short sleeve covering only the top of the shoulder, often with no underarm seam.
- Short. Ending on the upper arm, above the elbow.
- Elbow. Ending at or just below the elbow.
- Three quarter. Ending around the middle of the forearm.
- Bracelet. Longer than three quarter, ending just above the wrist bone so a bracelet shows below it.
- Long. Reaching the wrist.
- Extra long. Past the wrist and over part of the hand, deliberate on oversized knitwear.
Three quarter and bracelet are the pair worth being careful with. They are close enough that a photo rarely settles it, and shops treat them as different lengths. If a search on one is returning nothing, the other is the first thing to try.
Where does the fullness in a sleeve sit?
Volume is what gives a sleeve its character, and it is described by where the fullness sits rather than by how much there is.
- Fitted. Following the arm along its length.
- Straight. Even width from shoulder to opening, with no shaping.
- Puff. Gathered at the shoulder so the fabric stands up and out at the top of the arm.
- Balloon. Full along the whole sleeve, usually gathered at both ends.
- Bishop. Full through the forearm and gathered into a cuff at the wrist.
- Bell. Fitted at the top, then widening steadily so the opening flares.
- Flute. A shorter, softer bell, usually ending near the elbow.
- Leg of mutton. Full at the shoulder and tight from the elbow down.
- Blouson. Full through the body of the sleeve and gathered into a band, so it blouses over the cuff.
What kind of cuff is that?
The cuff is the smallest of the four reads and the one shops describe most precisely, because it affects both the look and the price.
A plain hem is a finished edge with nothing added. A ribbed cuff is a knitted band that grips the wrist, standard on sweatshirts and bombers. A buttoned cuff fastens with one or two buttons and sits flat. An elasticated cuff gathers without a visible fastening. A tie cuff closes with fabric ties. A split cuff is left open at the seam. A French cuff is double length, folded back and fastened with cufflinks rather than buttons.
French cuffs are worth naming when you see them because they are unmistakable in a photo: the wrist shows a doubled thickness of fabric and a small metal fastening instead of a button.
What does the armhole do to the fit?
One more thing the shoulder decides, and it explains why two garments with the same shoulder type can still fit differently.
A high, small armhole holds the sleeve close to the body and lets the arm move without dragging the whole garment. A low, deep armhole drops the underarm seam towards the ribs and makes the garment read as relaxed, which is deliberate on oversized knitwear and shirts.
Shops rarely name it directly, so it is not a search term. It is worth reading anyway, because a deep armhole is a reliable sign that the piece is cut oversized even when the body looks a normal width.
What if the sleeves are rolled up in the photo?
More sleeve searches fail on this than on anything else here, and it is entirely avoidable.
People roll their sleeves. A long sleeve rolled twice reads as a three quarter sleeve in a photograph, and if you search for a three quarter sleeve you are searching for a garment that is not the one in the picture. The shop is selling it as a long sleeve.
The tell is the fold. Rolled fabric bunches, sits thicker than the rest of the sleeve, and often shows a visible edge where the cuff has been turned back. A sleeve genuinely cut to three quarter length ends cleanly at a hem the same thickness as the sleeve above it.
The same trap applies at the shoulder. A sweatshirt pulled off one shoulder reads as an off-shoulder cut, and a shirt with the sleeves pushed up reads as fitted when it is not. Search what the garment is, not how it is being worn.
How do you turn a photo of a sleeve into a search?
A screenshot of someone in a cream top. The seam joining sleeve to body runs diagonally from the armpit towards the collar. The fabric stands up and out at the top of the arm, then narrows. The sleeve ends at the wrist in a gathered band with no visible button.
Shoulder: diagonal seam to the neckline, so raglan. Length: reaches the wrist, so long. Volume: full at the shoulder and narrowing, so puff. Cuff: gathered with no fastening, so elasticated.
The phrase is cream puff sleeve top elasticated cuff. Raglan comes out of the search rather than into it, because on a top like this the shop is much more likely to write puff than raglan. Keep it in reserve for narrowing if the results are too broad.
Can a sleeve tell you what decade a garment is from?
If you are trying to place a piece in time, the sleeve is the most reliable single detail, more so than the neckline or the hem.
Full shoulders read as either the 1890s or the 1980s depending on the rest of the garment. A narrow, high-set sleeve with a small armhole suggests mid-century tailoring. A drop shoulder in a heavy knit reads as contemporary. A tight bishop sleeve on a floaty fabric reads as 1970s.
This matters practically, because if the sleeve is telling you the piece is from another era, current retail vocabulary will describe it accurately and find nothing. That is the point to move to a resale search, using the era rather than the shape.
Does Snagfit name the sleeve for you?
Snagfit returns a short phrase on material, pattern or cut for each garment it finds, and a dramatic sleeve usually lands in that field: a puff, a bell or a balloon is distinctive enough to register.
Subtler sleeve information generally does not. Cuff type, the difference between three quarter and bracelet length, and the shoulder construction are all small in the frame, and on a full-length photo the sleeve occupies a narrow strip at the edge of the subject.
So this is a detail worth adding by hand rather than expecting back. Take the garment name Snagfit gives you, then put the sleeve word in front of it yourself.
Which sleeves have no name to search for?
Layered sleeves are the main gap. A sheer sleeve over a fitted one, a knit with a shirt cuff showing beneath it, a slip dress worn over a long sleeve top: in every case the photo shows two garments and the sleeve you are describing may belong to the one you are not searching for.
Detachable sleeves are the other. Some garments are sold with sleeves that tie or button off, and the listing describes the piece in its sleeveless state. If a sleeve looks oddly separate from the body of the garment, that is worth considering before you search on it.
