Sidewinder High Waisted Trousers in Caramallow

Independent design-led sleepwear + homewares brought to you by real people who care. We’re serious about Design + serious about Joy! 

£52.50
£75.00

Organic Cotton Sleepwear so good that 90% of our customers don’t want to confine it to the bedroom. Why? 

 

Designed in Glasgow by Mil, we describe our pyjamas as lightly tailored with a nod to workwear, and believe the maxim “the details make the design”. 

 

Our high waisted trousers feature twin needle stitching, gently tapered legs slightly cropped at the ankle, a double faced hem that can be rolled up (or let down), a drawstring waist with button-closing reinforced fly, a high waistband designed to sit in the small of the back, tailored with darts in the back for a comfortable and flattering fit.  

Colours:

Size

NB. our sizes 5, 6 + 7 are graded for plus size bodies and feature a bigger "front rise" designed to accommodate tummies, and a gusset for ease of movement. Sizes 0 - 4 feature 'regular' grading.  💚

Size guide

Size and fit

 

 

Why is our sizing so confusing? Click here for a 60 sec video from Jolene.

 

For the best fit, grab a tape measure and measure both your waist and the widest part of your bottom/hips and refer to our detailed size charts to find your size.

Great Service

My first order didn't fit but the customer service from Jolene and the team was second to none when it came to sorting me out with the correct size. I now have a pair of very comfy, funky trousers that I'm very happy with!

Brilliant designs and wonderful customer service

Just wanted to say a huge thank you again to the team at Irregular Sleep Pattern. Although my order of PJs had to be returned due to not fitting the correspondence form Jolene was brilliant along with a. speedy return process. I will most certainly be ordering from IRP in the future as I felt so valued and trusted as a customer. Thanks for your warmth and good will.
