Shelves are just going to atteact more clutter. Closed storage is what you should be aiming for.

Can you post pictures of the entire room, all 4 walls?

I would try to consolidate some of the furniture into closed storage

Vertical use of the room to maximize storage.

There are many options, even building in cabinets of your own configuration like you would a kitchen set up. Hanging storage, drawers, a vanity, desk. if you measure the room, and take the measurements to your local home improvement store, they will FOR FREE, design a storage plan to suit your needs. get a quote, no commitment to purchasing, but the best way to find out what is possible.

Add a vanity with some good storage and a place to do hair and makeup.

Thank you everyone for your advice!
Here are more pics of the room.

This is what I was originally going for, but I think you all are right... it may look even more cluttered.

I just bought a cart for her to place all the products that are currently cluttering up her dresser and vanity. Hopefully that will help,

Can you give room dimensions with window placements dimensions too.

I hope this makes sense

Here is a map of the room... I hope it makes sense,
What should I do with this wall? Remove the shelf and place a wall mirror?

Please indicaate where the door is to enter the room.

Just a thought: let's include your daughter in your post. "Hey, daughter, let's do a facelift to your room. I've posted on houzz, and all are ready to hear your ideas."

I'll definitely include my daughter.

Here's a furniture layour of for suggestions.

Possibilities & look for bed in window wall

So here's a quick layout of what you could do. The colors should be to your daughter's taste, so this is only one idea out of a million things you could do. The sleigh bed, while pretty, takes up a lot of visual space so I'd suggest swapping it out with something less "heavy", unless you can't afford to do that right now. Sometimes you just have to use what you have right now, and that's okay. Shop on Walmart, Amazon, thrift stores/consignment to find fun pieces that will work for her needs.

The basket makes a nice place to put dirty laundry or throw blankets.

I like darker walls since her furniture is light, but you can tone it down if it's too dark. My daughter selected a dark avocado green in high school and pairs it with fushia and that was really pretty too. A rug is a fun piece to good way to start and then you can select colors from that, if you decide to use one. Soft pillows and throws are fun on the bed too for a teen girl.

Love this so much!! Thank you!!

Some thoughts from the trenches. . . my kids NEVER used the desks in their bedrooms except for surfaces to dump a lot of stuff - total waste of money and space. They did their studying on their beds, the floor, the sofa, etc. If she's a reader a slim bookcase might be a better option - could be used as a bedside table. A large oversized pillow or beanbag chair for floor-sitting would probably get a lot of use. You might want to focus on a closet organizing system with shelves, bins and hooks so all that "stuff" has a place to land and leave more floor space for teenage lounging. A full-length mirror on the back of the door will be appreciated by a teenage girl. Consider where she can charge her electronic devices. Once I accepted the reality of how my teens actually lived in their rooms v.s. my fantasy, life got more relaxed for all of us. Enjoy her - these years are gone in a flash!

Thank you einportlandor! I needed to hear this message.
