There's 10 Matryoshka Dolls in the early access version of Visage. Of these 7 are lootable at any time inside the house and 3 are missable during unique sequences. To simplify it, there is 1 doll in each unique section "outside" the normal house in Lucy's Chapter.

For the most convenient experience I recommend grabbing the 7 dolls inside the house at the very beginning of the game or after a chapter of it so you can avoid foes hunting you. I put the mildly spoiler location ones at the end of the guide.

In the house

1. Progress Room
Inside the desk



2.Son's Room
Between the wardrobe and some boxes. It's hard to spot.



3. Parent's Bedroom
In the bottom right drawer of the dresser.



4. Dining Room
In the middle upper cabinet.



5. Secret Room
In the Garage Attic. Reach it by moving the large toolbox and crawling through.



6. Basement hallway
Where there is a lot of insulation on the walls, it's between some steps on the short staircase.



7. Basement Storage
It's in the freezer in the room where you first hear Lucy.

Missable dolls outside the house

8. Treehouse
It's under the radio in the corner.



9. Cage Room
After the chase sequence out of the Cage Room you'll find it next to the miniature wardrobe in the room with the dolls in the wall.



10. Wardrobe Room
After reaching the giant room of wardrobes you'll find one inside a wardrobe near the center of the room. To make it appear open the wardrobe and take a picture to see a bunch of masks show up.
