    The Modern Sleeping Beauty

    I absolutely love my new Dagsmejan nightgown! The quality, comfort and softness is truly exceptional. I prefer to sleep on a gown but it’s difficult to find a warmer gown that doesn’t look like I borrowed it from my granny. The fit is flattering and when I put it on I feel wrapped in a coziness like a princess.

    I was between sizes and sized down (thanks to reviews).

    This was my first purchase but will not be my last!
