Back to School: Uniform Alteration Tips for Parents

Prepare for the new school year with our practical guide to school uniform alterations.

School uniform alterations

The back-to-school season can be stressful for parents. Between buying supplies and organising schedules, ensuring uniforms fit properly often falls to the last minute. Here's how to get ahead with school uniform alterations.

Common School Uniform Alterations

Trouser & Skirt Hemming

The most common alteration for school uniforms. Children grow at unpredictable rates, and hems that were perfect in June may be too short by September. Professional hemming ensures a clean finish that won't unravel.

Blazer Adjustments

School blazers are expensive, so it makes sense to buy big and have them altered. Sleeves can be shortened and taken in at the sides. As your child grows, sleeves can often be let out again.

Waist Adjustments

Many children are between sizes. If trousers fit at the waist but are too long, or fit in length but gape at the waist, alterations are the answer.

Money-Saving Tips

  • Buy bigger, alter smaller: It's easier to take things in than let them out
  • Bundle alterations: Many seamstresses offer discounts for multiple items
  • Hand down and alter: Older siblings' uniforms can be altered for younger ones
  • Check seam allowances: Quality uniforms often have generous seams for letting out

When to Book

August is the busiest time for school uniform alterations. Book at least 2-3 weeks before school starts. Better yet, get a head start in July when seamstresses have more availability.

Name Labels & Embroidery

Many seamstresses also offer name label embroidery, which is more durable than iron-on or sew-in labels. It's a worthwhile investment for items that will be washed frequently.
