Can Ironing Really Cause Silk to Shrink?

Before we dive in too deep, let’s first tackle the question that brings so many silk devotees here: does ironing make silk shrink?

The short answer is yes, silk can absolutely shrink if ironed improperly or carelessly.

But have no fear! With smart precautions and the right technique, it’s totally possible to smoothly iron out wrinkles without compromising the size or shape of your treasured silk pieces.

What exactly causes silk to shrink? Two main culprits are to blame here:

  • Heat – Silk fibers are extremely sensitive to high heat. Exposing them to excessively hot irons can distort the proteins and cause the fabric to shrink up.
  • Moisture – Water swells and expands the silk fibers. If they then dry in this expanded state, the fabric takes on a smaller size compared to before it got wet.

Many folks also wrongly assume that all silks shrink equally with heat or water. In truth, the amount of shrinkage depends heavily on the type of silk fabric:

Fabric TypeDescriptionShrinkage Potential
HabotaiTypically seen in liningsHigh
ChiffonDelicate, lightweight fabricHigh
Crepe de ChineTextured and wrinkledMedium-High
CharmeuseHas a satiny side and a matte backLow-Moderate
DupioniMade from irregular silk threadsLow-Moderate

As you can see, it’s imperative to know your silk type before breaking out the iron!

3 Key Factors That Determine Shrinkage

More than just the silk variety, three key factors come into play when it comes to potential heat-related shrinkage:

1. Water Quality

  • Using hard tap water introduces minerals that damage silk fibers.
  • Distilled water with minerals removed is ideal for steam-ironing silk.

2. Iron Temperature

  • Excessive heat distorts silk proteins, risking major shrinkage.
  • The optimal iron temp for silk is low to medium (250°F to 300°F).
  • Always start low (silk setting) and increase heat cautiously as needed.
Silk VarietyRecommended Iron Temperature
Habotai230°F – 250°F
Chiffon230°F – 250°F
Crepe de Chine250°F – 275°F
Charmeuse275°F – 295°F
Dupioni275°F – 300°F

3. Pressing Technique

  • Maintaining proper ironing direction and motion prevents over-stressing fibers.
  • Hovering the iron over delicate areas also helps prevent direct heat damage.

Now that you know what makes silk shrink, let’s talk about preparing your delicate silk garments to face the iron!

4 Must-Do’s Before Ironing Silk

You’ll be ready for wrinkle-free, shrink-free ironing success by taking these key precautions upfront:

  • Test for colorfastness – Dampen a hidden area and press with a white cloth. If any dye transfers, dry clean only!
  • Select a gentle iron & cover – Opt for an iron with precise temp controls and use a 100% cotton press cloth.
  • Know your water – Fill your iron with distilled or filtered water to prevent mineral buildup and contamination.
  • Pre-wash similar fabrics – Like with like! First wash silk companion fabrics (lining, trim, etc) before ironing garments.

And the most important pre-ironing step…

Use a Press Cloth!

This specialist cloth shields delicate silk fibers from direct heat damage during ironing.

  • 100% lightweight cotton works best
  • Dampen cloth thoroughly before pressing
  • Avoid thick terry towels – trap excess moisture

Step-By-Step Guide to Ironing Silk Safely

Follow these simple steps to smoothly remove wrinkles and creases without distorting or shrinking your precious silk garments:

Prepare the Garment

  • Button up closures so seams align flat
  • Check inside-out for tangled lining or pads
  • Gently pull the fabric in shape on a padded surface
  • Lightly dampen thick silk with a spray bottle

Begin Ironing

  • Arrange silk smoothly on the ironing surface
  • Place damp press cloth directly over the silk panel
  • With the iron safely on its stand and unplugged, slide the iron on top of the press cloth
  • Apply light pressure while slowly guiding the iron across the fabric
  • Lift the iron completely every few inches

Caution – never leave powered iron sitting directly on silk!

Target Wrinkled Areas

  • Isolate tough wrinkle spots and hover the iron closely over the damp cloth
  • Allow steam to penetrate and relax the fibers
  • Avoid repeated passes over the same area

Finish Up

  • Give the entire garment surface a once-over pass while the iron rests on the cloth
  • Leave the damp cloth over the silk until fully cooled
  • Check for missed spots and touch up if needed

3 Iron-Free Ways to De-Wrinkle Delicate Silk

When you’d rather not pull out the ironing board, try these no-heat methods to smooth out delicate silk:


  • Use a handheld garment steamer with a silk/delicate setting
  • Lightly hover the steamer head over the wrinkles
  • Slowly move the head across the garment surface

Bathroom Steaming

  • Hang the silk piece in the bathroom before showering

Store Silk Properly After Ironing

Preserve your lovely silk pieces between wears by:

  • Letting garments fully cool before folding or hanging
  • Storing offseason items in breathable cotton
  • Placing tissue paper between silk before storage bagging
  • Allowing silk to rest 24 hours before wearing
  • Dry cleaning whenever overly soiled from wear

Avoid cramming freshly ironed silk pieces into crowded closets or dirty laundry piles. Give those elegant fabrics room to breathe!

What Not to Do When Ironing Silk

Here are the biggest ironing mistakes to avoid with delicate silks:

  • Leaving powered iron stationary on fabric
  • Using tap water containing minerals
  • Over-wetting silk prior to ironing
  • Repeatedly going over the same spot
  • Failing to use lower silk/delicate heat setting
  • Ironing lining and shell fabrics separately
  • Storing ironed silk without allowing it to fully cool

Trust me, we’ve all been there! But now that you know better, you’ll do better. And your precious silks will thank you!

Now what about intentionally trying to shrink your slightly baggy silk item down to size – can an iron help? Let’s find out.

Can You Safely Shrink Silk with an Iron?

I’ll be upfront on this one – shrinking silk garments intentionally with an iron is strongly not advised!

While giving silk pieces a tighter fit with heat and moisture is technically possible, extreme caution is mandatory.

Attempting to arbitrarily shrink fine silk often leaves behind permanent damage like:

  • Distorted seams
  • Deformed buttonholes
  • Patchy glossy marks
  • Melted or fused fabric

If you’re struggling with iron scorch marks on silk, here’s how I managed to get rid of them.

However, I understand the temptation to shrink a slightly loose silk blouse or slip dress to achieve that perfect customized fit.

So whether you decide to attempt this risky endeavor or not, here are my top safety tips:

Carefully Inspect Seams & Details

Thoroughly examine the entire garment inside out first for:

  • Fragile stitching
  • Non-silk fabric blends
  • Beading, embroidery, or other delicate decor

Choose Only Medium-Grade Silks

Sturdier weaves like these are the most shrink-resistant:

  • Dupioni
  • Charmeuse
  • Habotai (the riskiest option though)

Prep & Press Strategically

  • Lightly steam the entire inside-out garment
  • Stretch and smooth flat while damp
  • Press only the exterior side with a cloth
  • Target loose waist, hip, cuff areas

Work Slowly in Sections

  • Divide the garment visually into quarters
  • Lift and hover iron frequently
  • Alternate with gentle tugging/smoothing
  • Allow to fully cool between sections

Stop at ANY Sign of Damage

  • Melting, glossy spots
  • Puckering seams
  • Distorted buttonholes

Immediately abort mission if shrinking seems uneven or you notice any fabric distortion!

While I can’t guarantee safe shrinking results, taking these extreme precautions gives you the best shot.

Though, personally, I suggest embracing the oversized silk look or paying a tailor to take in certain areas instead!
