Duvet thickness matters more than nightwear
Short answer: If the duvet is too warm, thin sleepwear will not fix it. Choose the duvet based on the bedroom temperature and use bedding to fine tune the rest of the comfort.
The duvet sets the frame
A winter duvet in a room at twenty degrees is too warm no matter what you sleep in, even the thinnest sleepwear cannot correct that mistake. The duvet's warmth level determines far more of your sleep comfort than sleepwear and bedding combined, which is exactly where you should start. See bamboo bedding.
Bedding fine tunes the rest
Thin bamboo viscose bedding wicks away moisture and feels cooler against the skin than thick cotton, which traps both heat and moisture all night long. This kind of fine tuning is what makes the difference between a good night and a bad one, once the duvet itself already roughly fits. See home homewear in bamboo.
Two duvets in one bed
If you sleep at different temperatures, two duvets are the only real solution, rather than trying compromises that rarely work well for both people. With a duvet each, both can choose thickness independently, without either one having to freeze or sweat for the other's sake. See bamboo sleepwear for women.
Switch duvets with the season
A summer duvet and a winter duvet cover the year for most people, and the difference in warmth level is often bigger than it first appears. Switch at the change of season along with your wardrobe, so you always sleep under a duvet that suits the temperature outside. See bamboo sleepwear.
The duvet's fill matters
Down holds warmth better than synthetic fill of the same thickness, which means a down duvet can often be thinner and still provide the same warmth as a bulkier synthetic one.
Room temperature should be measured, not guessed
Most people judge bedroom temperature by feel, but a simple thermometer gives a far more accurate picture of what is actually happening in the room at night.
Signs the duvet is wrong
If you wake up clammy, kick the duvet off in your sleep, or feel cold constantly, it is usually the duvet rather than the sleepwear that needs adjusting first.
Consider a duvet that splits
Some duvets come in two sections that button together, making it possible to adjust the warmth at each end of the bed independently, based on what each person needs.
Combine it with room ventilation
Even the right duvet helps less in a room without fresh air. Air the room out before bedtime, so the temperature drops naturally and the duvet has an easier time holding a comfortable warmth through the night.
