About the Omi dress

The Omi dress is a relaxed, mid-thigh button-up dress with a collar. The design was inspired by a vintage, well-loved dress that I found in my maternal grandmother’s (my “Omi”’s) wardrobe that always reminds me of how effortlessly stylish she was, even on the most average of days. Pop on the Omi dress with some loafers for a clean, sophisticated day look; dress it up with a jean jacket, chunky sandles, and a few bits of jewelry to meet a friend for a cocktail; or toss it over a swimsuit for a beach picnic. Versatile, comfy, and classy, the Omi dress fits in (and stands out) just about anywhere summer might take you.

The Omi dress is worked top-down, mostly in stockinette stitch with clean double-stockinette finishes. It’s knit flat and is virtually seamless—except one small bit of seaming to complete the armhole finishes.

Gauge information:
19 stitches / 23 rows in stockinette stitch, worked flat = 10cm x 10cm after blocking

Please note that making and blocking a gauge swatch is extra important and strongly recommended for this pattern, as the target gauge is a little atypical for a DK weight yarn. Friends, skip swatching at your own risk.

Yarn selection tips

Choosing a yarn weight: This pattern is designed to have a relaxed, moderate drape. To achieve this in the designer’s sample, I used a larger needle size than is typically recommended for DK weight yarn, paired with a pure wool yarn to ensure a “bouncy” fabric—one that’s lightweight and fluid without becoming limp or losing its shape.

If you choose to deviate from pure wool (for example, by using a cotton, linen, or bamboo blend), be aware that these fibers lack wool’s natural elasticity and “bounce”. In those cases, you may find it easier to achieve the target gauge and desired fabric density by choosing a yarn that falls closer to a worsted weight. Regardless of your fiber choice, I strongly recommend swatching and blocking to ensure you love the look and drape of the resulting fabric.

Choosing a yarn fibre: The right yarn fibre for the Omi depends largely on your local climate:

• For moderate climates (under 25°C / 75°F), I highly recommend superwash merino wool. It keeps you at a comfortable temperature even when there’s a slight coolness in the air, and offers a beautiful drape, crisp stitch definition, and a smooth finish that feels lovely.

• For hot and/or humid climates (over 25°C / 75°F), merino can get a bit toasty! To stay cool, try a yarn that blends wool with a plant-based fiber like cotton or linen. Just note that you may get a drapier fabric that grows a bit more than wool on blocking.

• I’d generally suggest avoiding heavy insulators like cashmere, alpaca, or mohair, as they might be too warm for this style. But hey, you do you if you have a vision!*
