Choosing a tailor

How to Tell if Suit Fabric Is Real (Selvedge, Burn Test, Mill Books)

Question answered: “How do I know the fabric is really Italian / cashmere?”

By Tony Ram, Second-generation owner, Peninsula Bespoke Tailor · Updated

To check suit fabric is genuine, look for the mill name woven into the selvedge (the fabric's edge), ask to see the mill's swatch book, and feel it: real wool is springy and recovers from creasing. A burn test on a loose thread also helps: wool smells like burnt hair and turns to ash, while polyester melts into a hard bead.

Can a selvedge be faked?

Yes, sometimes. That's why mill swatch books and a tailor's reputation matter as much as a woven name.

Frequently asked questions

What is a selvedge?
The finished edge of a fabric roll, where mills often weave their name.
Is a wool blend bad?
Not always. Wool-linen or wool-silk can be excellent. The problem is fabric sold as something it isn't.
Can I do a burn test in the shop?
Ask the tailor for a loose thread first.
