Shortening a jacket sleeve the tailored way with a lining placket
A new jacket that fits the shoulders perfectly but hangs an inch or two past the wrist is one of those small frustrations that can ruin an otherwise lovely garment. In Australian boutiques from Chapel Street in Melbourne to Queen Street in Brisbane, ready-to-wear blazers and coats tend to be cut for overseas sizing blocks, which means sleeves that often swamp the arms of anyone under 170 cm tall. Rather than paying $60 to $120 at an alterations counter in Sydney's CBD or risking an uneven chop with the kitchen scissors, shortening a jacket sleeve with a lining placket is a satisfying weekend project that leaves no visible trace of the work.
The lining placket is the small faced strip inside the cuff opening that finishes the raw edge neatly, and it is also the part most home sewers are afraid to dismantle. The good news is that, with a sharp seam ripper, a thimble and a little patience, you can release the original hem, shorten the lining, reattach the placket and have the cuff looking exactly as the maker intended. This method works on lined blazers, trench coats, school uniforms and even some of the heavier wool blends stocked at Spotlight and Lincraft across the country.
Setting up your workspace and tools
Before the scissors come out, a tidy workspace saves time. A flat dining table cleared of breakfast plates works well, and if you live in a Sydney or Perth apartment, a cutting mat laid over a sheet of A2 cardboard protects both the bench and the blade. Australian summers can climb above 38 °C in Adelaide and inland Queensland, so if you don't have air conditioning, set up in the morning before the heat makes the lining fabric cling to your fingers.
Tools to gather include a seam ripper with a sharp point, tailor's shears with at least 20 cm blades, fine hand-sewing needles in sizes 9 and 10, silk or polyester thread to match the lining, a thimble, a steam iron with a pressing cloth, glass-headed pins, a measuring tape, tailor's chalk and a pressing ham or rolled tea towel. The Australian Consumer Law gives you the right to expect goods of acceptable quality, so if your jacket is brand-new and the sleeve was mislabelled at the counter, the retailer may cover the cost of alterations or offer a refund. Keep the receipt and the swing tag handy before you unpick a single stitch.
Measuring and marking the sleeve
Try the jacket on over a thin jumper or shirt you would normally wear underneath, then stand in front of a full-length mirror. Bend the elbow and rest the arm at your side: the sleeve should fall to the base of the thumb with about a centimetre of ease. Anything more than that is fair game for taking up.
Mark the new hemline on both sleeves while the garment is on the body, using pins placed at the side seam and the underarm seam. Take the jacket off and lay it flat on the table. Measure the distance between the old hemline and the new one on the outside sleeve, and write the figure down on a scrap of paper so both sleeves match. A useful Australian habit is to keep a small notebook of every alteration you make, including the date, the garment and the change in millimetres. Over time this becomes a personal size file that makes ordering from international pattern houses such as Simplicity, New Look or Burda much more predictable.
The notebook also helps when you measure a sleeve lining that has dropped or shrunk in the wash, because the figure you need is the difference between the old hem and the new one, not the absolute length. As a sanity check, hold the original hem allowance against the new mark: if there is less than 3 cm of spare fabric inside the cuff, it is worth buying extra lining before you start, and most Spotlight stores keep a small range of cupro and bemberg on the bolt.
Working with the lining placket
Turn the sleeve inside out and locate the placket: it usually runs about 8 to 10 cm along the inside of the cuff opening, finished with a small strip of lining fabric that folds under itself. Slip the seam ripper under the stitches and unpick the hem of the outer sleeve first, then the hem of the lining. Take out only as much stitching as you need to release the excess length, and leave the side seams and the top of the placket untouched.
Press the freed cuff flat with a damp pressing cloth, so any small creases from the original hemline disappear. If the lining has a vent at the cuff, slip a pin through it before you begin so the two layers don't shift, and fold the placket back exactly as it sat before. Many tailors in Melbourne's inner north will tell you that the placket is the soul of a jacket sleeve: get this step right and everything else is plain sailing.
Measure the excess fabric inside the cuff: it should equal the difference between the old and new hemlines, plus 2 cm for the new fold. If the lining has shrunk more than the outer fabric, which often happens with rayon and viscose linings after a humid Sydney summer, trim it back to match the wool, not the other way around. The pressed crease technique shown in this folding guide is worth consulting at this point, because the lining needs to sit in a flat, even line before any stitching begins.
Comparing methods for the cuff finish
Different jacket styles call for slightly different approaches once the placket is free. The table below compares the three most common finishes used in home sewing circles across Australia, including the techniques shared by local makers on Instagram and Pinterest boards.
| Method | Skill level | Tools needed | Best for | Time required |
|---|---|---|---|---|
| Hand-stitched blind hem | Beginner to intermediate | Needle, matching thread, thimble | Wool blazers, school uniforms | 45–60 minutes per sleeve |
| Machine blind hem | Intermediate | Sewing machine with blind hem foot, thread | Cotton and linen jackets | 20–30 minutes per sleeve |
| Decorative topstitch | Confident sewer | Machine, contrast thread, edge foot | Trench coats, statement jackets | 30–40 minutes per sleeve |
Pick the method that suits the fabric weight and the way you wear the jacket. A wool blazer from David Jones in Sydney is forgiving of a hand-stitched finish, while a polyester-cotton trench from a Kmart seasonal range responds well to a quick machine blind hem. For heavier melton or boiled wool, a decorative topstitch in a contrasting colour can be the difference between a hidden alteration and a deliberate design feature.
Stitching the new cuff
Fold the excess lining up to the new hemline, slip the placket back into position and pin the lot horizontally across the cuff. A horizontal pin keeps the layers from sliding while you stitch. Use a single strand of silk thread for a wool sleeve and a doubled polyester thread for a synthetic one, so the stitches sit neatly inside the lining without abrading the skin of the wrist.
Work from the inside of the sleeve with a ladder stitch, also called a slip stitch, along the folded edge of the lining. Take tiny 2 mm bites of the outer fabric so the stitches vanish into the wool. At the placket, fold the facing back along its original crease and slip-stitch it down by hand, hiding the knot between the layers. If you are nervous about this step, practising on a sleeve cut from an old cotton sheet first is a forgiving way to build confidence.
Once both sleeves are done, turn the jacket right side out and put it on. Cross the arms in front of the chest, then raise them above the head: the hem should stay put without binding. If the lining pulls when you move, ease the stitches and redistribute the fabric. Most home sewers find that a millimetre or two of extra length on the lining, about 5 mm, prevents the lining from peeking past the wool at the wrist, especially on long car trips from Brisbane to the Gold Coast where the air-conditioning can make the lining stiffen and ride up.
Final pressing and adjustments
Give each finished cuff a final press with a damp cloth and a warm iron, hovering rather than pressing hard so the wool does not shine. Lift the sleeve and slide a rolled tea towel inside the cuff so the seam sits over a curve and presses out flat. If the jacket is a school blazer from a Queensland or Western Australian uniform shop, the standard expects a crisp, smooth finish without visible stitching, so spend an extra minute at this stage.
Brush the surface with a soft garment brush to lift any chalk marks and remove loose threads. Hang the jacket on a wide wooden hanger, since plastic wire hangers from dry cleaners distort the shoulder line over time, particularly through a humid Hobart winter. Store it on the hanger with a breathable cotton cover, never a plastic dry-cleaning bag, which traps moisture and encourages mildew on wool and silk linings.
For anyone wanting to take their handmade wardrobe further, exploring embroidery and surface decoration is a lovely next step once the jacket fits beautifully. The same precision and patience that goes into a clean cuff carries across to other fibre projects, and how to create a personalized embroidery hoop art pairs especially well with a freshly tailored blazer as a weekend companion piece.
A shortened sleeve that still has its lining placket intact is one of those small alterations that quietly transforms how a jacket feels on the body. The shoulders sit better, the arms move freely and the whole silhouette looks considered rather than borrowed. With the original cuff opening preserved, the jacket will also hold its resale value on platforms such as Depop and eBay Australia, where buyers in Melbourne and Adelaide pay a premium for pieces that have been altered by hand rather than chopped to fit.
If you would like more sewing notes, pattern walk-throughs and fabric diaries from Australian sewing rooms, the Victoria Lucille Anne blog gathers guides, project logs and links to longer video walk-throughs on YouTube. It is where the next jacket, and probably the next lining placket, gets planned out in full.
