We were surprised at how difficult it was to find a classic, pretty cotton nightie that wasn't super sexy, overly romantic, or kind of sheer. The Sleeveless Nightie fills that gap, and it has been one of our bestselling items since we launched it a few years ago. A soft blue twill cotton fabric, featuring a subtle diagonal weave that adds texture and depth to the smooth material.
- Knee-length nightie with flared body
- Adjustable, gathered neckline
- 100% cotton
- We describe this fabric as crisp, medium-light weight, and opaque.
- Cold water wash and hang dry, take care of your nightie and it will last you for years
- Made in Canada with pride
