How to Alter a Coat That Is Too Big or Small?

Altering a coat that is either too big or too small can be a cost-effective and sustainable way to update your wardrobe.

Whether you’ve lost or gained weight, inherited a coat, or found a vintage gem, making it fit perfectly can breathe new life into an otherwise neglected garment.

Here’s a step-by-step guide on how to alter a coat:

Materials You’ll Need:

• Coat in need of alteration
• Seam ripper
• Pins
• Sewing machine or needle and thread
• Fabric chalk or tailor’s pencil
• Measuring tape
• Iron and ironing board
• Scissors

For a Coat that is Too Big:

Try On the Coat

Begin by standing in front of a full-length mirror with good lighting. Take your time to assess how the coat drapes on your body.

Pay close attention to the shoulders, sleeves, torso, and waist. Note if the shoulders are slipping down, if there’s excess fabric around the torso, or if the sleeves are too long. This initial assessment will guide you in pinpointing the areas that need adjustment.

Pin the Excess Fabric

Using straight pins, gently gather the excess fabric along the areas that need alteration. Start at the shoulders and work down, pinning along the seams.

Be meticulous about maintaining a balanced look, ensuring the coat retains its natural shape and symmetry.

Remove Excess Fabric

Lay the coat on a clean, flat surface. With a seam ripper, carefully and methodically undo the stitches along the areas you’ve pinned.

Take your time to avoid stretching or damaging the fabric, especially if it’s delicate or prone to fraying.

Re-sew the Seams

After removing the excess fabric, fold the remaining fabric to the desired size. Pin it in place to ensure it stays secure. Select an appropriate stitch length using a sewing machine and sew along the pinned seams.

For hand-sewing, use a backstitch for added durability. Take care to maintain consistent tension for a professional finish.

Adjust the Lining

If the coat has a lining, carefully align it with the altered outer fabric. Pin it in place and sew along the original seam lines.

This step ensures that the lining and outer fabric sit harmoniously, maintaining the coat’s overall structure and appearance.

Press the Seams

Preheat your iron to a suitable temperature for the fabric. Lay a pressing cloth over the altered areas to protect them from direct heat.

Apply even pressure and glide the iron along the seams, smoothing any wrinkles or creases. This step is instrumental in achieving a polished and professional look.

Trim any Excess Fabric

With sharp scissors, carefully trim any remaining excess fabric. Exercise precision, leaving a small allowance to prevent fraying. Take your time and cut with deliberate movements to achieve clean, neat edges.

Finish with Details

Thoroughly inspect all closures, such as buttons, zippers, or snaps. Make any necessary adjustments to ensure they align perfectly with the new fit.

Also, double-check for strength and durability if any areas were reinforced during the alteration process.

For a Coat that is Too Small:

Assess the Situation

Put on the coat and stand comfortably, allowing yourself to move freely. Please pay close attention to how it feels around the shoulders, arms, chest, and waist.

Take note of any noticeably tight areas. Stand before a mirror to visually assess the fit, ensuring the coat drapes well.

Use Seam Ripper

When the coat has seams that can be let out, carefully and methodically use a seam ripper to undo the stitches.

Work with precision, taking your time to avoid accidentally damaging the fabric. This step allows for additional room in areas where the coat is too snug.

Add Extra Fabric

In cases where letting out seams is not an option, consider adding fabric panels for expansion. Measure the specific areas that require more room and cut matching fabric pieces.

Pin and baste them in place, ensuring a seamless integration with the original fabric. This method provides a tailored solution for achieving a comfortable fit.

Cut and Attach Extra Fabric

Cut the fabric pieces with meticulous care, paying close attention to the grain and pattern matching. Pin them in place and sew with precision.

The objective is to integrate the additional fabric seamlessly, creating a cohesive look that complements the original design.

Adjust the Lining

Since alterations were made to the lining, carefully reattach it. Match the seams with the outer fabric and sew along the original seam lines.

This step is crucial in ensuring that the lining and outer fabric work harmoniously to maintain the coat’s overall structure.

Press the Seams

Preheat your iron and set it to the appropriate temperature. Place a pressing cloth over the fabric to protect it from direct heat.

Gently press along the seams, smoothing out any wrinkles. This process contributes to a refined and well-finished appearance.

Trim any Excess Fabric

Utilize sharp scissors to trim any remaining excess fabric carefully. Exercise precision, leaving a small allowance to prevent fraying. Pay close attention to detail to achieve clean, polished edges.

Finish with Details

Confirm that all closures align correctly with the new fit. Make any necessary adjustments to ensure they function smoothly.

Double-check for strength and durability if any areas were reinforced during the alteration process. This final step ensures that the coat is well-fitted, fully functional, and aesthetically pleasing.

Caring for the Altered Coat

Caring for an altered coat is crucial to maintaining its newly tailored fit and ensuring its longevity.

Here are some essential tips for caring for your altered coat:

Storage

When storing your coat, select a location that is cool, dry, and shielded from direct sunlight. Avoid cramming it into a crowded closet, as this can lead to wrinkling and distortion of the fabric. 

Instead, opt for a broad, padded hanger that supports the coat’s shape over time.

Cleaning

Adhere closely to the care instructions indicated on the garment’s label. 

If feasible, entrust the cleaning process to a professional dry cleaner, especially if your coat is crafted from delicate or specialty fabrics. Their expertise ensures that your jacket receives the precise care it requires.

Spot Cleaning

If there are minor stains or spills, promptly address them with a gentle fabric spot cleaner. Alternatively, gently create a solution of mild detergent and water to blot the affected area gently with a clean cloth. Avoid vigorous rubbing, which can exacerbate the stain or damage the fabric.

Avoid Over-Washing

Resist the urge to over-wash your coat. Excessive cleaning can lead to unnecessary wear and tear on the fabric. 

Only launder the coat when visible dirt or stains are present or after several wears. Consider using a fabric freshener spray to maintain a fresh scent between washes.

Avoid Harsh Chemicals

Exercise caution and refrain from using harsh chemicals such as bleach on your coat. These substances can cause irreversible damage to the fabric and may alter its color or texture.

Instead, opt for gentle, non-abrasive cleaning products designed to preserve the integrity of the fabric.

Proper Drying

Should your coat become wet, allow it to air dry naturally. Avoid exposing it to direct heat sources like radiators or hair dryers, as excessive heat can cause the fabric to shrink or warp.

Ensure the coat is hung or laid out in a well-ventilated area until completely dry.

Avoid Excessive Folding

To prevent the formation of creases and wrinkles, refrain from folding your coat for extended periods. 

If circumstances necessitate compact storage, gently drape it over a chair or sturdy hanger. This helps preserve the coat’s original form and structure.

Seasonal Inspection

Before the onset of each new season, thoroughly inspect your coat. Scrutinize for wear and tear, loose seams, or missing buttons. 

Addressing these issues promptly prevents them from escalating and preserves the coat’s overall condition.

Avoid Heavy Items in Pockets

Exercise caution when utilizing the pockets of your coat. Refrain from overloading them with heavy items, which places undue stress on the fabric. Distribute the weight evenly to preserve the coat’s fit and comfort.

Troubleshooting Common Issues
