Coastal Granddaughter style has this special way of blending beachy ease with a fresh, youthful twist that I can’t get enough of.
It’s not just about decorating—it’s about crafting a space that feels like a warm shore day, even when the world outside turns chilly.
My friend Sarah’s shore house opened my eyes to this look, and ever since, I’ve been hooked on its soft hues and cozy charm.
Think creamy whites, gentle blues, and sandy neutrals, all mixed with textures that make you want to kick back and stay awhile.

You’ll find plenty of ways to make it your own, from wicker accents to pastel pops, without any stiff rules holding you back.
I’m all about spaces that feel welcoming and real, not overly polished or fussy.
So if you’re ready to turn your bedroom into a sunny escape that lasts, let’s dive into these ideas together.
