Frequently Asked Questions

What makes your products better than other brands?

Our products are made from a variety of innovative, high-performance materials built to wick moisture, resist wrinkles and stretch in all the right places. Every item is designed to provide next-level comfort, flexibility, and durability, without compromising a sharp, work-ready aesthetic. You can learn more about specific fabric platforms on our Fabric Technology page

Are your pieces machine washable?

“Low-maintenance apparel” is our mantra - all of our garments are machine washable, and most can be tumble dried on low. We do recommend hang-drying suit jackets and laying our sweaters flat to air dry. Always check the care label on each item for specific instructions.

What’s your shipping and returns policy?

We offer free returns on unworn items in their original condition (undamaged, unwashed, tags attached) within 30 days of purchase, and free exchanges for store credit within the first 100 days after purchase, unless marked Final Sale or Exchange Only. Store credit is redeemable online at ministryofsupply.com or in-store. Learn more here.

Where is your clothing manufactured?

Our clothing is made in a variety of locations around the world, including domestically and in Asia. We carefully select manufacturing partners who share our commitment to high-quality craftsmanship, ethical labor practices, and sustainability. All of our production undergoes third-party inspection. Learn more about our factories.

What are your sustainability practices?

We take great pride in our sustainability initiatives - using durable, bio-based and recycled materials, utilizing zero-waste computerized knitting, and incorporating eco-friendly fabrics into many of our designs. We are constantly improving our processes to minimize environmental impact, from garment creation to reaching your doorstep. Learn more here.

Can you help me find my size?

We recommend using the size guides and fit tips available on each product page to find your perfect fit. You can also use the TrueFit widget to determine your recommended fit based on height, weight and body type. Our clothing is designed with a modern fit and generous stretch, so keep this in mind while shopping.

Do you test your products? What tests do you use?

At Ministry of Supply, we rigorously test our products to ensure best-in-class performance, durability and comfort - to that end, each product we make undergoes 50+ ASTM/AATCC tests, including:

  • Moisture-Wicking Tests to ensure fabrics effectively pull sweat away from the skin, keeping you dry and comfortable throughout the day.
  • Stretch and Recovery Tests to ensure pieces stretch comfortably and return to their original shape without sagging or losing form.
  • Temperature Regulation Testing to keep you cooler in the heat, and warm in cooler conditions.
  • Odor Control Tests to ensure that the fabrics maintain freshness even after prolonged wear.
  • Wash and Wear Durability Tests to make sure your clothes will withstand daily use and retain their sharp aesthetic for years to come.
