It’s great that you have a style in mind for your space, because that helps redecorating so much easier! Singular pieces and small effects over time will add up and definitely reflect the new feminine, industrial vibe you’re going for.
Without seeing a picture of the room, here are my best recommendations for places to start:
Freshen up the walls with a light color like a very pale pastel — this will bring in the feminine vibes but not be too bold as to take away from the more minimalist, industrial theme.
Add some tall shelves (maybe some DIY Rope Shelves!!) or buy an inexpensive model. This is great for storage and will also give you an opportunity for styling plants and other decor elements!
Pick up a nice big area rug to add some cozy and texture to that tile floor
For the bed, opt for clean white bedding and mix print throw pillows! These are a great place to bring in accent colors!
Hang tall panel curtains over your windows to maximize the room height and make your space feel elegant and open!
I hope these help! Excited for how your room is going to come out!
