Start with the size chart, not the age label
The Pax Playsuit in Vintage Denim is sized from 0–3 months up to 3 years, but the age on the tag is only a starting point. Each size has a specific length and waist measurement, and the playsuit includes adjustable shoulder straps with metal buckles that let you fine-tune the fit as your child grows.
Measure your child's length (from shoulder to crotch) and waist, then compare those numbers to the size chart below. The playsuit has elasticated leg openings that help keep the fit snug without being tight, but the length and waist are the key numbers to check.

How to wash the vintage denim playsuit
The Pax Playsuit is made from 98% cotton and 2% elastane, which gives it a soft, breathable feel with a gentle stretch. To keep the denim colour and the fabric's shape, follow the care instructions carefully.
Wash the playsuit in a laundry bag on a delicate cycle, using cold water only. Cold water helps prevent the dark denim dye from bleeding onto other clothes. Do not tumble dry—hang the playsuit immediately after washing to air dry. Always follow the care label instructions on the garment.
Simple wash routine for the Pax Playsuit
- Place in a laundry bag: Use a mesh laundry bag to protect the metal buckles and the leather patch on the front pocket.
- Wash in cold water only: Cold water helps remove excess dye from dark colours and prevents fading. Avoid warm or hot water.
- Do not tumble dry: Air drying on a line or flat surface keeps the elastane fibres from breaking down. Hang the playsuit immediately after washing.
- Follow the care label: The sewn-in care label provides the most specific instructions for your garment. Check it before each wash.
Styling ideas for everyday wear
The vintage denim stripe and leather patch give the Pax Playsuit a classic, slightly refined look that works for playdates, family outings, or casual days at home. The elasticated leg openings make it easy to pair with soft socks or booties, and the snap buttons at the crotch make nappy changes quick.
For cooler weather, layer a long-sleeve bodysuit or a simple knit top underneath. The adjustable shoulder straps let you raise or lower the bodice slightly, which can help the layering piece peek out neatly.
