Size Guide: Finding Your Perfect MOI Fit

At MOI, we believe the best clothes are the ones you don’t even feel on your body. Our natural linen pieces are designed for freedom of movement, a relaxed casual style, and absolute self-confidence.

We have moved away from generalized size charts. Instead, we provide precise measurements for every single item, ensuring your new favorite piece fits exactly the way you want it to.

The 2-Minute Size Hack

Since 100% natural linen is a non-elastic fabric (it doesn't stretch), we recommend measuring your favorite comfortable clothes instead of your body.

  1. Pick a garment made of non-stretch fabric that fits you perfectly.

  2. Lay it on a flat surface (a table or bed) and smooth out any wrinkles.

  3. Use a measuring tape to follow the guide below and compare your results with our tables.

  • B — Width Under Armholes: Half-chest width (from one side seam to the other).

  • C — Sleeve Length: From the shoulder seam to the end of the cuff.

Pro Tips for the Best Fit

  1. Between sizes? Always size up. This creates the modern, relaxed "oversized" silhouette that allows the natural fabric to drape beautifully.

  2. Adaptability. Many of our pieces feature tassels, elastic cuffs, or removable belts, allowing you to customize the fit to your mood.

  3. Care Guide. Natural linen loves gentle care. Machine wash on a delicate cycle at no more than 20°C (68°F) without harsh bleaches. Iron on the reverse side.
