What is Son of a Tailor?

At Son of a Tailor we do things differently. We are the first company in the world to create T-Shirts made to our customers' individual measurements, one at a time. All of our T-Shirts are made in Europe under working conditions of the highest standards.

How can I check the status of my T-Shirt order

You can log in to your profile page and check the status of your T-Shirt here. You are, of course, also, more than welcome to contact us for details.

What does 100% custom fitted / made to measure mean?

This means that no two Son of a Tailor customers will ever get the same T-Shirt. We make every T-Shirt specifically to each of our customers. This is possible either by measuring your body, measuring your favorite T-Shirt, or by using our smart Ideal Size™ algorithm to calculate your measurements.

Can I trust the Ideal Size™ algorithm results?

Yes, you can. The Ideal Size™ algorithm uses well established machine learning techniques to calculate your body measurements. Our algorithm is based on measurements from over 10.000 people from all over the world. From the 4 questions we ask, we are able to determine your body measurements with a 95% accuracy. Should the T-Shirt not fit perfectly, we will make you a new one free of charge.

How does your perfect fit guarantee work?

Should the unfortunate occur that the T-Shirt does not meet your specifications or expectations, simply let us know and we will make you a new T-Shirt free of charge. Write us at and we will take care of you.

Do you really offer free worldwide shipping?

Yes. We offer a selection of shipping options, always including at least one free option, no matter how big or small the package is. We ship from the EU, and agreements with Canada, Switzerland and Norway mean that you should not incur any fees in your order. All other local customs and handling fees are the responsibility of the customer.

How do I reorder a T-Shirt?

You can reorder from your profile page here. If you want to order the exact same T-Shirt simply press “reorder” and the T-Shirt will be added to your basket. If you want to make changes before you buy press “modify & reorder” and make changes to either the measurements or styling of the T-Shirt.

How do I contact you guys?

How long does it take from order to delivery?

We aim to deliver every custom order within 7-14 days. In case this cannot be adhered to, you will be notified when placing the order. All custom T-Shirts created at Son of a Tailor are unique items. Each item is individually cut, and our tailors hand-sew, and tailor your shirt exclusively to your preferences. One shirt at a time. No T-Shirts are produced from pre-cut patterns.

What is the difference between the Medium and Heavy fabrics?

The Medium is made from 150g/m2 jersey 100% Extra Long Stapled Cotton. It has a breathable and soft body feel due to the lighter knitting and quality of materials. The Heavy is a 200g/m2 jersey 100% Extra Long Stapled Cotton.

Is it necessary to compensate for shrinkage when writing my measurements?

No, we will add the necessary shrinkage percentage to the pattern so it shrinks to the correct size after a couple of washes.

How should I wash my T-shirt?

For a long life, wash at 40C with similar colors. Do not tumble dry. Using an enzyme free detergent and garment bag is best for your wool items.

Where is it produced?

The cotton fiber is produced in the US, then turned into yarn in Switzerland and, finally, the jersey is produced in Portugal. The Merino wool is from selected producers in Australia. Our T-Shirts are developed and manufactured in Portugal.
