Tailoring 101: Master the basics of fit adjustment
Good tailoring is the difference between clothes that fit and clothes that flatter. Here's how to assess what needs adjusting and when to call a professional.
5 min read · IrisTailoring isn't luxury—it's practical. A $40 shirt that fits your shoulders perfectly is worth more than a $400 one that pulls at the seams. The goal of tailoring is simple: make your existing clothes work harder for your body, not the other way around.
Whether you're hemming jeans, taking in a waistband, or adjusting sleeve length, understanding the basics helps you communicate clearly with a tailor and recognize quality work. Some alterations you might even tackle yourself with patience and a needle.
A well-fitted garment in your closet beats a trend-perfect one hanging unworn in the back.
Step one · 2 minutes
Identify what needs adjusting
Start by trying on the garment and noting where it doesn't fit. Common issues: hems that drag, sleeves that swallow your wrists, waistbands that gap, or shoulders that slope too wide. Take photos or notes. The most impactful alterations address length (hems, sleeves, inseams) and width (taking in seams, adjusting darts). Don't try to fix everything at once.
Wear the shoes and undergarments you'll pair with the piece when assessing fit. A hem length looks different in flats versus heels.

Understand the cost-to-benefit ratio
Not every piece deserves alteration. A $20 fast-fashion shirt might cost $30 to hem—not worth it. A well-made blazer or pair of trousers? Absolutely. Consider the fabric quality, how often you'll wear it, and whether the alteration is structurally simple or complex. Seam adjustments and dart work cost more than hemming because they require more skill.
Budget $20–$40 for basic hemming, $40–$80 for taking in seams, and $60–$150 for complex work like sleeve reconstruction.

Find a tailor you trust
Ask friends for recommendations or check reviews for local tailors. Visit in person with a garment you've already had altered to assess their work. A good tailor listens, asks clarifying questions, and doesn't upsell unnecessary changes. They should explain what's possible and what isn't. Chemistry matters—you'll be returning.
Bring a garment that fits you well to show your tailor as a reference for how you like things to sit.
Step four · 10 minutes
Communicate clearly at the fitting
Wear the piece with the shoes and undergarments you'll pair it with. Show your tailor photos of how you want it to fit if you have them. Use specific language: 'I want the hem to hit at my ankle bone' rather than 'make it shorter.' Point to where seams should sit. Listen if they suggest alternatives—a tailor's expertise is valuable. Never rush this conversation.
If you're nervous about an alteration, ask if they can do a test run or partial adjustment first.
Step five · 2 minutes
Inspect the finished work before paying
Try on the altered garment in the tailor's shop if possible. Check that hems are even, seams are straight, and the fit matches what you discussed. Look at the stitching quality—it should be small and consistent. If something's off, speak up immediately. A reputable tailor will make minor adjustments for free.
Examine the inside of hems and seams. Hand-stitched work looks different from machine work, but both can be excellent.

Build a relationship with your tailor
Once you find someone good, stick with them. Return customers get priority, better rates, and tailors who understand your preferences. A tailor who knows you'll anticipate your needs and offer solutions before you ask. This relationship is an investment in your wardrobe's longevity.
Tip your tailor 15–20% for quality work, just as you would a stylist or barber.
How to know tailoring worked
A successful alteration is invisible. The garment should fit your body without pulling, gaping, or bunching. Seams should sit where they're meant to, hems should be even and appropriately weighted, and you should feel confident wearing it. The best sign? You reach for the piece repeatedly.
Questions at the mirror.
How do I know if a garment is worth tailoring?
Consider the original cost, fabric quality, and how often you'll wear it. A well-made piece you love is always worth tailoring. Fast fashion or pieces you're unsure about usually aren't.
Can I tailor stretchy or delicate fabrics?
Yes, but it requires a skilled tailor. Knits, silks, and elasticated fabrics need special handling. Ask your tailor about their experience with the specific fabric before committing.
What alterations are impossible?
Making a garment significantly larger is difficult if seams are tight. Changing the neckline or armhole dramatically requires reconstruction. Always ask your tailor what's feasible before hoping.
How long does tailoring usually take?
Simple hems take 1–2 weeks. Complex work like taking in seams or adjusting sleeves takes 2–4 weeks. Rush services cost more. Ask for a timeline upfront.
