Beautiful but too small in some areas

Just received this slip in the mail today! Was so excited to get it as I’ve been in search of a nice black slip to be able to enjoy for sleeping as well as dressing it up to wear out! I love idle, the fabric feels so nice and is elegant and feminine but also feels strong and well made. I’m a size 12/14 and bra size is 36/38C depending on the brand/style. I ordered the XL/1X as that size is supposed to fit a 16/18. I wanted the top area to fit loosely (add a belt around my waist for everyday wear), but the bust area was too tight and ended up pushing my chest down awkwardly. It’s odd that it fit so tightly on my chest as it’s a whole 2-3 sizes bigger than my regular size. The rest of the dress fits as loose as I was expecting! Just a little disappointed in the chest area. Still a beautiful piece, which is why I’ll size up again!

Lucious and versatile slip!

I love my new Idle slip. It is so comfortably, silky and smooth to the touch while still keeping me cool. The fact that it is washer/dryer friendly is a game changer. I love slips but never feel like they fit my shape. This one is totally different though: the dart in the back makes it way less restrictive and more flowy and flattering. Love the look of it so much that I wear it at home and out as well. New favorite piece <3

The Fabrics

Super soft, cool to the touch, and earth-friendly, too. Made with plant-based fibers like cupro and tencel, our fabrics are sustainably sourced and with no animal byproducts, completely cruelty-free.

The Fit

We worked hard to create a fit that works for more bodies, so each style is available up to 3X. Focusing on creating extra room in the chest and waist without adding to the length, our fits stay flirty, not frumpy.

The Care

Our styles are hypoallergenic, anti-static, stretch-resistant, and thermo-regulating, so you can lounge longer and wash less. Plus the more you wear it, the softer it’ll get. To keep your Idle looking and feeling its best, machine wash cold and hang or lay flat to dry.
