Openings: how a garment lets your body in
Before a single button or zip, the shape of the opening decides whether you lift a garment over your head, reach behind you for a sleeve, or simply put it on like a coat.
Pullovers, front openings and the arm that goes in first
Tops let a body in one of two ways. A pullover is a closed tube you get into by lifting it over your head. A front-opening top, such as a cardigan, shirt or zip jacket, splits down the middle, so you put it on like a coat and close it afterwards. The first costs a lift; the second costs a fastening.
Which is easier depends on which move is harder for you, and the public guidance reflects that. An occupational therapy handout from St Vincent's Hospital Melbourne (read 19 October 2026) calls front-opening shirts and cardigans the easiest tops when dressing with one hand. A children's guide from St. Jude (read 19 October 2026) suggests pullover shirts, which have no buttons at all. Both are right: one is avoiding the fastening, the other the reach behind.
Both sources agree on the order. The arm or side that moves less goes into its sleeve first, and comes out last when undressing. The stronger arm then has the whole garment to work with. For a front-opening top this also shortens the reach behind your back for the second sleeve.
Neck openings and how far a head has to travel
On a pullover, the neck opening decides most of the effort. A narrow ribbed crew neck has to stretch around the widest part of the head, which takes both arms pulling outward at shoulder height or higher. A scoop or V neck, a boat neck or a wide crew lets the head through with less stretch and less time with the arms up. The carer guidance from the University of Worcester (read 19 October 2026) makes the same point plainly: the size of the neck opening matters for how easily a garment goes on and comes off.
Fabric changes the picture. Jersey and knit give at the neck; a woven shirt collar does not give at all. A loose body helps the second half of the job, pulling the garment down, because it does not cling at the shoulders. In listings, neck shape is usually visible in the main photo; neck width is easier to judge from a flat-lay than from a photo of a model.
Half zips, side openings and other partial openings
Between the pullover and the full front opening sit garments that open part of the way. A half-zip or quarter-zip sweatshirt opens at the neck, so the head goes through a wide gap, then the zip closes a short distance. Its zip is closed at the bottom, which means it works with one hand while the other holds the hem, or with no hold at all on heavier fabric.
Some garments open at the shoulder, along a sleeve or down a side seam. The daywear advice on Living made easy (read 19 October 2026), the Disabled Living Foundation's advice site, notes that shoulder and sleeve openings can help a person dress themselves. On mainstream catalog shelves these are rare; side zips on tracksuit trousers and button shoulders on some knit tops are the ones you are most likely to meet.
Henley tops, with a short buttoned placket at the neck, behave like a half zip with small buttons: the opening helps, the fastening may not.
Reaching behind your back, and the garments that make you
Three things on a garment put your hands behind your back: a fastening that sits there, a second sleeve that has swung round behind you, and a hem or waistband that needs pulling straight at the back. The first is the hardest to avoid without changing garment. A zip down the back of a dress, hooks at the back of a top, a tie at the back of a waist: each needs a hand at or above the middle of the back, often with a pinch at the end of it.
The same Living made easy page puts the trade-off clearly: back openings can make it easier for a carer to dress someone, while front fastenings make it easier for a person to dress themselves. If you dress alone and reaching behind is the hard move, choose front or side fastenings, wrap styles, or no fastening at all.
For the second sleeve, a loose armhole and a smooth lining shorten the reach; a stiff, close jacket lengthens it. For the hem, a looser body that drops on its own does the work.
Both arms overhead: what a pullover really asks
Putting on a pullover usually goes like this: gather the body up to the neck, put one arm into its sleeve, then the other, then lift the neck opening over the head and pull the garment down. The lift is short but it happens with both arms up, often while the face is covered by fabric, which is when balance and shoulder movement both matter.
Carers are taught a variation that shortens the lift: put both arms in first, as far as the elbows, then take the garment over the head with the arms already inside. The University of Worcester guidance describes it as diving in arms first. Dressing seated removes the balance part of the problem; see the seated dressing page.
If arms overhead is the move you want to avoid entirely, the pullover shelves are not where to look. Cardigans, zip-fronts, shirts and wrap styles all go on like a coat.
Coats and outer layers: the second sleeve
An open-front coat avoids pulling the whole garment over the head, but reaching the second sleeve can still be difficult. Check the opening, weight and lining against a coat the wearer already manages. Do not assume every garment called a coat has the same opening or that a smooth lining resolves a restricted movement.
In practice, a few things shorten that reach: draping the coat over a chair back and backing into it, putting it on seated, or choosing a cape or poncho, which drops over the shoulders with no sleeves to find. Lighter jackets with roomy armholes are easier than close-cut jackets.
Then comes the fastening. Most coats close with a separating zip, buttons or both; the fastenings page compares them.
