Comfortable Trimmed Pyjama Set
This product is a two-piece pyjama set from Miiyu by Simons, an exclusive line designed in Canada, comprising a long-sleeve button-front shirt and matching capris. It is made from 100% organic cotton jersey, with the shirt featuring full-length buttons, matching trim, and a chest patch pocket, while the capris have a covered elastic waistband with drawcord and a back patch pocket. It is designed for sleep and loungewear, is machine washable, and reviews indicate that while most wearers find it true to size, some report the sleeves and pant length run short.

Product Insights
Miiyu's Comfortable Trimmed Pyjama Set offers a nursing-friendly design with a button-front top that provides one-handed access, a chest pocket for phone storage, and breathable organic cotton jersey that wicks moisture and vents heat to reduce night-sweat disruptions, while minimizing skin friction and chemical residues for sensitive-skin comfort, but buyers must contend with sleeves and pants that run short (e.g., ending 6 inches above the wrist at 5'5") and a cotton fabric that may shrink further in the wash, requiring cold washing and low heat drying, sizing up, or accepting a cropped fit, and note that returns are only possible if the set is unwashed. Softness improves with each wash, and pilling is minimized by gentle cold washing inside out, making it a charming new-mother gift that doubles as loungewear.

Deep Research
Button-front pajama top practical uses
- The full-length button placket lets a nursing mother open the top with one hand for breastfeeding without pulling the entire garment over her head, a feature postpartum guides consistently rank as essential for midnight feeds — and one this set delivers even without explicit maternity branding.
- The patch pocket at the chest keeps a phone, lip balm, or tissues within arm’s reach during 2 a.m. wake-ups — a small convenience that eliminates fumbling on the nightstand and is often cited in nursing pajama roundups as a practical plus.
- Worn open over a tank or buttoned as a casual shirt, the button-front top transitions from sleepwear into daytime loungewear — a useful quality for the early postpartum weeks when a more pulled-together look for visitors is desired without changing out of pajamas.
- Because the shirt opens completely at the front, it slips on and off without raising the arms overhead — a literal relief for anyone recovering from a C-section, mastectomy, or shoulder injury, where lifting a pullover top can be painful or restricted.
Why organic cotton jersey for sleepwear
- Organic cotton jersey actively pulls perspiration away from the skin and disperses it through the fabric, keeping the body dry — this moisture management is what makes the set functional for hot sleepers and prevents the clammy, sweat-drenched awakenings that synthetic blends often cause.
- The gentler processing chain — skipping the harsh bleaching, mercerizing, and resin finishing that can coat conventional cotton fibers — leaves the organic jersey with a rounder, smoother hand that minimizes skin friction through eight hours of movement, which directly translates to less nighttime scratching and fewer micro-abrasions on sensitive or eczema-prone skin.
- Because organic cotton is grown without synthetic pesticides and processed without formaldehyde or harsh dye-leveling agents, this 100% jersey set leaves substantially fewer chemical residues on skin compared to conventional cotton sleepwear — for someone with eczema, sensitive skin, or even mild nighttime itching, that lower payload can be the deciding factor between restful and irritated sleep.
- Because organic cotton breathes well enough to stay dry, it denies dust mites and bacteria the warm, humid microclimate they need to proliferate, making the pajama set an inherently less hospitable environment for allergens — this is especially relevant for people whose nasal congestion or skin flares seem tied to bedding.
- Without chemical stiffeners or resin finishes that can wash out, this 100% organic jersey gets softer with each wash rather than pilling or stiffening, so the set’s lived-in feel actually improves over time instead of degrading — a meaningful point for a garment that sees a machine wash after every wear.
- The open fiber structure of organic cotton jersey creates continuous micro-ventilation that wicks body-warmed air away and draws cooler air in, stabilizing body temperature throughout the night — this is the active mechanism behind why organic cotton sleepwear helps prevent overheating without the need for special cooling fabrics.

Smaller than expected
I have always found size large in the Miyu pyjama sets a perfect fit. Unfortunately this set is comparatively smaller. Since they have been washed I sadly can no longer return them. The fabric is lovely, however.

Very short sleeves and pants.
I ordered the correct size (from chart and other Simon products I have bought). However, at 5'5", the sleeves were about 6 " from my wrist and the pants were cropped. (Strange, as I find that most tops have sleeves that are too long). And this was not how they were shown in the photo. They appeared to be well made. (AND there is one pocket on the back of the pajama bottoms).

Beautiful pattern
Beautiful pattern and very soft material. I love that it’s 100% cotton. I’m typically a small, but the x-small fit well at the waist. Unfortunately, the pants don’t have pockets.

Q&A
4 answered- Does this pajama set run true to size, and is the organic cotton jersey pre-shrunk to minimize shrinkage after washing?
- We recommend following the size chart for the best fit. Organic cotton jersey can shrink in the first wash if not pre-shrunk; washing in cold water and tumble drying on low heat can minimize shrinkage.
- What is the recommended washing and drying method to maintain the fabric's softness and prevent shrinkage?
- We recommend washing the set in cold water on a gentle cycle and tumble drying on low heat to maintain the fabric's softness and minimize shrinkage. Avoid bleach and high heat.
- How accurately do the product photos represent the actual colors, especially for patterns like 'Flower' and 'Polka Dot'?
- We strive to make product photos as accurate as possible, but colors may vary slightly depending on your screen settings. The patterns like 'Flower' and 'Polka Dot' are represented faithfully in our images.
- How does the fabric hold up to repeated washing in terms of pilling, fading, and shape retention?
- With a 4.5-star average from 18 reviews, customers generally report good quality. Organic cotton jersey can develop some pilling over time, but washing inside out and on a gentle cycle helps preserve the fabric's appearance and shape.
