Modifying a t-shirt for shoulder surgery recovery takes about 10 minutes per shirt and requires nothing more than scissors, a fastener of your choice, and a shirt that’s one size larger than you normally wear. The basic idea is simple: cut open the sleeve and shoulder seam on your surgical side so you can drape the shirt on without lifting your arm, then reattach the cut edges with a closure you can manage one-handed.
Start With the Right Shirt
Grab t-shirts that are at least one size bigger than your usual fit. You need room for bandages, swelling, and the sling itself to sit comfortably underneath. A shirt that fits perfectly before surgery will feel tight and restrictive after it. Loose, soft cotton is the easiest fabric to work with and the gentlest on healing skin. Cotton breathes, absorbs sweat, and washes easily. Bamboo fabric is another strong option since it’s softer than cotton and naturally antibacterial, which is a bonus when you’re dealing with incision sites. Avoid anything synthetic or stiff that could rub against surgical dressings.
Old t-shirts you don’t mind cutting up are ideal for practice, but even shirts you care about can be modified cleanly enough to wear again after recovery.
Where and How to Cut
Lay the shirt flat. On the surgical side, cut from the bottom hem straight up through the side seam, continuing through the armpit and along the shoulder seam to the neckline. You’re essentially opening the entire side of the shirt so it can lay flat and wrap around you. Some people prefer to also cut along the bottom of the sleeve from armpit to cuff, which gives even more room for a bulky sling.
If your surgery is on the right shoulder, you cut the right side. Left shoulder, left side. The unmodified half of the shirt goes on first: slide your good arm through its sleeve, pull the shirt over your head, then drape the cut side over your surgical shoulder and close it up.
Cut in a straight line as close to the original seam as possible. This gives you clean, even edges to attach your fasteners to and keeps the shirt looking relatively normal from the front.
Choosing Your Fastener
You have three main options: Velcro (hook-and-loop tape), snaps, and magnets. Each has trade-offs worth knowing before you commit to modifying several shirts.
- Iron-on Velcro is the fastest option. You can seal it onto the cut edges with a household iron or even a flat iron for hair. It’s easy to manage one-handed because the two sides don’t need to be perfectly aligned. The downside is durability: repeated washing collects lint in the hooks, which gradually weakens the grip. Closing the Velcro strips before tossing the shirt in the wash helps extend their life.
- Snaps give a cleaner look and hold up well in the wash. Snap plier kits are inexpensive and easy to use. The drawback is that snaps require more precise alignment when you’re fastening them one-handed, and poorly placed snaps can dig into skin when you lean against a chair or pillow. Think carefully about where your arm and body will rest before deciding on snap placement.
- Magnetic closures are the easiest to fasten with one hand since the magnets pull themselves together. They require gentle handling to stay aligned over time, and they shouldn’t be placed near a pacemaker or implanted defibrillator. These cardiac devices are designed to respond to magnetic fields, and magnets closer than about 6 inches (15 cm) to the implant can trigger unintended behavior. If you have a cardiac implant, stick with Velcro or snaps.
Step-by-Step: The Velcro Method
This is the most popular DIY approach because it requires no sewing.
Get iron-on hook-and-loop tape from a fabric or craft store. Cut it into strips about 3 to 4 inches long. You’ll need enough strips to run from the bottom hem, up the side seam, through the armpit area, and along the sleeve opening, spacing them roughly 3 to 4 inches apart.
Lay the shirt flat with the cut edges overlapping by about half an inch. Place the hook side of the Velcro on one edge and the loop side on the matching spot of the opposite edge, so they’ll meet when the shirt is closed. Use your iron on medium heat (or follow the tape’s packaging instructions) to seal each strip in place. Press firmly for about 15 seconds per strip. Let the adhesive cool completely before testing.
Try the shirt on with your sling before doing a whole batch. You want the closure to sit comfortably without gaps but also without pulling tight across the sling. Adjust your overlap or strip spacing on the next shirt if needed.
Snap Placement Tips
If you go with snaps, install them with the same spacing as the Velcro method. The key difference is placement: avoid putting snaps anywhere you’ll lean on during sleep or while sitting in a recliner. After shoulder surgery, many people sleep semi-upright, and a snap pressing into your ribcage or back at 3 a.m. is miserable.
Place snaps along the front side of the seam line rather than directly on the side seam. This shifts them slightly forward where there’s less pressure from your body weight. Along the shoulder and sleeve, snaps can sit closer to the top since you won’t be leaning on them there.
Adding an Ice Pack Pocket
If you want to go a step further, you can sew or pin a simple fabric pocket on the inside of the shirt at shoulder height. A rectangular piece of cotton fabric about 6 by 10 inches, stitched on three sides, creates a sleeve that holds a standard flexible gel ice pack against your shoulder hands-free. Position it so the pocket opening faces upward (toward the neckline) so the pack doesn’t slide out.
Some people add a second pocket on the opposite side of the collar for the back of the shoulder. This lets you alternate ice and heat packs without holding anything in place, which is especially useful in the first couple of weeks when icing is frequent.
How Many Shirts to Modify
Most people find four to six modified shirts are enough to rotate through laundry cycles during the first six weeks of recovery, which is the period when your arm is typically immobilized in a sling. After that, you’ll gradually regain enough range of motion to pull on a regular loose t-shirt, though some people continue using modified shirts for two to three months if their mobility returns slowly.
Consider modifying at least one button-up shirt as well for appointments or situations where you want to look a bit more put together. The same cut-and-fasten approach works on flannels and casual button-downs, and the existing front buttons handle the other side.
Dressing With a Modified Shirt
The process goes: surgical side first, good side second. Open all the fasteners on the modified side. Slide your good arm through its sleeve and pull the shirt over your head, letting the open side hang loose. Then drape the modified panel over your surgical arm and sling, and close the fasteners from bottom to top using your good hand. Reverse the order when undressing: open the fasteners first, then pull the shirt off over your head and slide your good arm out last.
Practicing this sequence a few times before surgery, while you still have full use of both arms, builds the muscle memory that makes those groggy first post-op days much easier.
