Your wardrobe, not a catalogue
Layerly only suggests clothes you have ticked as owned, so the outfit is one you can actually put on.
Most dressing advice for babies has the same flaw: it tells you what the perfect outfit would be, assuming you own the perfect outfit. A merino base layer, a fleece mid layer, a waterproof pramsuit, and a woollen hat, all in the right size, all clean, all in the hallway.
Real drawers are not like that. So Layerly was built around the clothes you actually have.
Tick what you own
During setup you go through a wardrobe checklist: bodysuits, sleepsuits, trousers, cardigans, fleeces, overalls, pramsuits, hats, mittens, socks, sleep sacks and their TOG ratings. Tick what is in the drawer, skip what is not.
In a hurry there is a quick setup that ticks a realistic starter wardrobe for you, and a detailed setup if you would rather be precise. Either way you can change it at any time — and you will, because babies grow out of things and seasons turn.
What that changes
Because Layerly knows what you own, it never recommends a fleece overall you do not have. It works with what is there: if you have no mid layer, it will build the warmth out of two thinner layers instead, or tell you honestly that today is colder than your wardrobe covers.
It also makes gaps visible. If your recommendation keeps stopping short on cold mornings, that is a useful signal about the one item worth buying — rather than a list of twelve.
Sleep, too
The same applies at night. Layerly picks from the sleep sacks you own, matching the TOG rating to the room temperature and adjusting the pyjamas underneath so the total warmth comes out right. If you only have a 2.5 TOG sack, it will say what to put under it rather than suggesting you buy a 1.0.
