Building a matching set of Christmas pyjamas for the whole family looks easy from the outside, until you get into the sizing. One print, spread across three different sizing systems, is usually where things start to go wrong.
A family of five choosing to match is not making one purchase decision, but five, spanning baby sizing in months, children's sizing in years, and women's and men's alpha sizing, all of which need to land in the same design. Our size guide is worth keeping open as you shop, and this page walks through the order to buy in so nobody gets left out.
How to Build a Matching Family Christmas Pyjama Set
Our matching sets are built so a single design carries all the way from baby sizes through to the largest adult size. Baby Christmas pyjamas in a family set use the exact same print as the adult sets, rather than something loosely related. Where the print is identical, the garment shape isn't: baby sizes are often supplied as sleepsuits rather than two-piece sets, and younger children's sets are cut with fuller trouser legs. That's entirely normal, and it's what makes a family photograph read as coordinated rather than uniform.
The order you buy in matters. Work outwards from the hardest size to find, not from your own.
Begin with the largest adult size in the group. Men's Christmas pyjamas and women's Christmas pyjamas both run through to the larger end of the adult range, with plus sizes on selected designs, and the top of each range typically sells through first. If someone needs one of the largest sizes, confirm it is in stock in your chosen print before adding anything else to the basket.
The oldest child comes next. Kids Christmas pyjamas run up to 14 years, and the 11 to 14 age band is the second constraint to check, since it tends to be the smallest part of most print runs. Dedicated boys and girls collections carry the same designs if you need a specific fit.
Everyone else can wait until last. Baby Christmas pyjamas and the younger age bands are the easiest to fill, and grandparents, a partner's family or a new baby can all be added at this stage. Selected prints extend to matching dog pyjamas so the pet can join the photo too. Add everyone before you check out, rather than trying to match the print in December when individual sizes will have gone.
For a two-person set rather than a full household, matching couples Christmas pyjamas carry the same designs in adult sizes only.
How Should I Size Children Who Are Between Ages?
Children's age bands assume an average height and build for that age, so if a child is at the top of a band in October, it's worth buying the next band up. The set has to survive two to three months of growth before it's actually worn, and a slightly loose pyjama set stays comfortable, while a tight one tends to get refused outright. Our size guide gives measurements rather than ages, which is the more reliable way to check.
Which Prints Work Best for Family Photos?
Three print families photograph reliably, whatever the size of the group. Avoid mixing two prints from the same colour family across the group: either match exactly or contrast clearly.
Tartan and check hold their structure at distance and in low light, which describes most living rooms on Christmas morning. A red or green check tends to be the most forgiving option when the group is standing at different depths from the camera.
Fair Isle and Nordic patterns read as festive without tipping into novelty, and they suit mixed age groups well, particularly where a teenager isn't going to wear a cartoon reindeer print.
For larger groups, plain colour with a single motif works best. Once you're past six people, a busy all-over print starts to become visual noise in a photograph.
Christmas Eve Pyjamas as a Family Tradition
The matching set is usually opened on Christmas Eve rather than Christmas Day, and that changes what's sensible to buy. These pyjamas get worn on Christmas Eve evening, slept in, worn through Christmas morning, and often worn again on Boxing Day, which adds up to roughly 36 hours of continuous wear before the first wash.
For that reason, cotton or brushed cotton is the safer buy over fleece. Fleece is warmer, but it holds heat through a full day indoors with the central heating on and a houseful of people, and it's the most common reason a family set gets abandoned by midday.
Children's pyjamas sold in the UK must also be labelled under the Nightwear (Safety) Regulations 1985 to show whether the fabric meets the flammability performance requirements of British Standard BS 5722. A black label reading LOW FLAMMABILITY TO BS 5722 means the fabric meets the standard, while a red label reading KEEP AWAY FROM FIRE means it does not. Worth a glance when a family set will be worn around a real fire, a log burner or an advent candle. Guidance is published by Business Companion, on behalf of the Chartered Trading Standards Institute.
