I have gone on a loungewear shopping spree [1] this week, but still, nothing compares to my Lou & Grey sweatsuit [2]. It's truly the softest set I've ever put on my body, without a doubt. The brand makes a line of sweats called Signaturesoft Plush, which they describe as feeling like "the most luxurious cashmere combined with your favourite sweatshirt." I think that nails it, because the fabric equates to wrapping yourself up in the coziest blanket on earth.
I own several colours of the Signaturesoft Plush Upstate Sweatshirt [3] ($70) and Signaturesoft Plush Upstate Sweatpants [4] ($70). Putting these pieces on brightens my day, because I know I'll be comfortable while I work from home, but I can stay cosy at night when I sleep in them as well.
The pieces are true to size (I'm wearing a large for reference) and don't shrink in the wash for me, which is awesome. Read on to shop the pieces I own and more options in this buttery-soft fabric. If you don't believe me, just read the customer reviews. This stuff is pure magic.
