A really simple dresser that matches the door or the headboard and maybe a bookshelf. Otherwise I think you're set.

Btw, is that a chair in the corner that's a highheel shoe? because I love that.

Normally I'd say do long dresser on wall opposite the bed because that would end up with the most balance, but then you'd likely have a mirror facing the bed, which is uncomfortable for a lot of people. Maybe try a cream wooden dresser on the wall adjacent to where shoe chair is now. Move shoe chair to corner by closet/bedroom. I'd do a glam mirror over the dresser. If she doesn't need a desk in this room, you could always give her a vanity and do the mirror over that instead of over the dresser.

Modern with chevron curtains, so the balance imo isn't toward more mirrored furniture - would be too glam. You want chevron's vibe right? Transitional wood dresser.

As to position of things - wondering if tree [decal?] couldn't be on wall to left... seems too art-patterned next to fancy mirrored stand or you think??

I'd put a long dresser opposite the bed. A mirror definitely in the room but make it full length. Above the dresser consider putting a picture ledge up so she can change pictures as she pleases with no holes or tape marks on the walls. Like the idea of a cream colored dresser, pretty and girly but won't upstage the bed and nightstands.

If there's a ceiling light fixture you know what you need to do! Little sparkly chandelier for sure. If not put a sparkly lamp on the new dresser. Seems like it should be shorter and wider than the bedside table lamp but you won't know that until you have the dresser in the room.

I have a Thomasville French that I just finished painting thats for sale. would look great! lol

I would agree with a long dresser, but no mirror. Stick to a long mirror on one of the sides of the rooms. Above the dresser I would use the wall for a painting. Also stick to a light color dresser to set aside from the side tables.

Like what others have mentioned already, I think a white or cream dresser would look best. Not only will it match with some of the existing furniture pieces, but it will also help brighten up the room a bit!

Don't match the night stands. White or cream would look great. This one's from IKEA:

Very nice room, did she pick the colors? I agree with a an off white dresser or cream.

Try a Parson's-like bench at the end of the bed with some B&W graphic bins or baskets to slide underneath for additional storage. I'd also consider placing a desk next to the bed where the tree stencil is to replace the 2nd nightstand, and find a fun fuzzy desk chair like they have at PB Teen for some added texture. Don't be afraid to put up some framed art gallery or photos of your daughter, perhaps in black and white to play off the theme. Good luck!
