Why does the shape of a jumper tell you so little?
A jumper is a jumper. The outline of a knitted top is one of the least varied in clothing: a body, two sleeves, an opening at the neck. If you search on shape you are searching a category of tens of thousands of products with nothing to filter on.
What separates knitwear is the surface. How thick the yarn is, what pattern the stitches make, and what the neck does. Those three, in that order, are how shops file it and how you should search it.
This is the opposite of outerwear, where the silhouette does all the work and the fabric is a footnote.
What is gauge on a knit?
Gauge is how many stitches fit into a given width, so it describes how fine or chunky the knitting is. It is the first read because it decides what season the garment belongs to.
- Fine gauge. Small tight stitches, reading almost as a smooth fabric from a short distance. Lightweight, often merino or cotton.
- Mid gauge. Individual stitches visible up close but not from across a room. The everyday jumper weight.
- Chunky. Large stitches clearly visible at a distance, with obvious depth to the surface.
- Super chunky. Thick yarn, individual stitches an inch or more across.
Reading gauge from a photo is one of the easier calls in this whole guide. Look at the shoulder or the chest at whatever zoom you have: if you can count individual stitches, it is chunky or above. If the surface reads as continuous, it is fine gauge.
What stitch pattern is that?
The stitch is the most searchable field on knitwear, because the patterns are distinctive and shops name them in product titles.
- Cable. Raised ropes twisting over each other in vertical columns. Unmistakable.
- Rib. Vertical raised lines with valleys between them, giving stretch across the body.
- Waffle. A grid of small raised squares across the surface.
- Moss or seed. A fine speckled texture with no direction to it.
- Jersey or stocking stitch. Flat and smooth on the front, with fine V shapes visible up close. The default.
- Pointelle. Small deliberate holes arranged in a pattern, giving a delicate open look.
- Aran or fisherman. Cables combined with diamonds and textured stitches, traditionally in undyed cream wool.
- Fair Isle. Bands of small repeating colour patterns worked around the body.
- Intarsia. A picture or block of colour knitted into the fabric rather than printed on it.
Rib is worth a note because shops describe its width. A two by two rib has narrow even columns; a wide rib has broader ones. Ribbing also turns up as trim at the cuffs and hem of garments that are otherwise knitted plain, so seeing rib at the wrist does not make the garment a rib knit.
Why does the neck matter so much on knitwear?
Knitwear is the category where the neckline does the most work, because with the shape and often the colour being unremarkable, the neck is what is left to distinguish two jumpers.
Crew, V neck, boat, scoop, mock, turtle, roll, funnel, cowl and shawl collar all appear on knitwear, and shops put them in the title far more reliably than they do on woven tops. The full vocabulary is in the necklines chapter.
The one distinction that matters most here is inside the turtleneck family. A turtleneck folds back on itself so there are two layers at the throat. A mock neck stands up without folding. On a photo of a knitted top, that fold is frequently the only thing separating two otherwise identical listings.
Is it a jumper, a cardigan or a sweatshirt?
Once gauge, stitch and neck are settled, the garment noun is straightforward.
A jumper or sweater pulls on over the head. A cardigan opens down the front. A knitted vest or tank has no sleeves. A knitted polo has a collar and a short button placket. A sweater dress is a jumper cut long enough to be a dress.
Jumper and sweater are the same garment in different markets, so if one returns little on a particular site, the other is the first thing to try. Vest is the trap: in British usage a vest can mean a sleeveless undershirt, so knitted vest or sleeveless jumper is safer.
Can you tell wool from acrylic in a photo?
Fibre affects the price of knitwear more than anything else, which is why shops list it prominently, and it is the field you should be most careful about.
Wool, lambswool, merino, cashmere, mohair, alpaca, cotton and acrylic all appear in listings. Mohair and alpaca are the two you can genuinely read from a photo, because both have a visible halo of long fine fibres standing off the surface.
Cashmere is the one people try hardest to identify and the one you should not guess. It has a soft halo and a slight sheen, and so does a good lambswool. Treat fibre as something to confirm on the listing rather than something to search on, unless the halo is obvious enough to be mohair.
How do you turn a photo of a jumper into a search?
A screenshot of someone in a cream knitted top. Individual stitches are clearly visible from a distance. Raised ropes twist over each other in columns down the front. There is a band at the neck standing up around the throat, and its top edge stops cleanly with no fold. The shoulder seam sits partway down the upper arm.
Gauge: stitches visible from a distance, so chunky. Stitch: twisting ropes, so cable. Neck: standing but not folded, so mock neck. Shoulder: seam below the shoulder, so drop shoulder, which is worth noting as a narrowing term.
The phrase is cream chunky cable knit mock neck jumper. Swap jumper for sweater if the site you are searching is American. Add drop shoulder only if the first search is too broad.
For the photography side of this, how to keep the stitch texture readable and what a worn jumper reveals that a shop photo does not, there is a separate post on finding a knit or sweater from a photo that goes further into the shot itself.
What does a worn jumper tell you that a shop photo does not?
Knitwear ages visibly, and a photo of a worn jumper carries information a listing photo does not.
Pilling, the small balls of fibre that form where fabric rubs, appears faster on softer and shorter fibres. Heavy pilling at the underarm and the sides on a garment that is otherwise in good condition points towards cashmere or a soft lambswool rather than a hard-wearing wool or acrylic.
Stretched cuffs and a dropped hem suggest a loose gauge and a heavy yarn. A jumper holding its shape after obvious wear is usually a tighter gauge or has some synthetic content. None of this is conclusive, and all of it is a better guide than trying to read fibre off the colour.
Is that crochet or knitting?
Worth its own section, because shops file it separately and a lot of searches fail on it.
Crochet is made with a single hook rather than two needles, and it makes a visibly different fabric: open and looped, with gaps between the stitches and a chunkier, more irregular texture than a knit of similar weight.
If the top in your photo has visible holes in a regular pattern and a rustic surface, search crochet rather than knit. Searching a knitwear term for a crochet garment will miss it entirely, and this is a common failure on summer tops and beach cover-ups.
What does Snagfit tell you about a knitted top?
Snagfit files a knitted top under Top and returns a shoppable name, the main colour and a short phrase on the material or cut.
Strong surface patterns are among its better reads: a cable, a chunky rib or a Fair Isle band is a large repeating texture that shows clearly even at a moderate size in the frame, and those are exactly the words that narrow a knitwear search.
Fine gauge is where it struggles, and reasonably so. A tightly knitted merino top photographed at a distance is visually a plain coloured top, and there is nothing in the image to say otherwise. On those, expect a general description and add the gauge word yourself.
Which knitwear cannot be found by name?
Hand knitted and vintage pieces are the main case. A hand knitted jumper is one of one, and its stitch pattern may not correspond to anything a shop sells. The vocabulary will describe it correctly and find nothing, which is the point to search resale by fibre and era instead.
Novelty knits are the other. When the interest is a picture knitted into the front, the gauge and the stitch are almost irrelevant to what you liked. Search the motif with the plainest possible garment word attached, and use intarsia only if the image is knitted in rather than printed on.
