How to Recreate Belly Conklin's Dreamy Coastal Bedroom From TSITP

Let me tell you something. You probably grew up with a bedroom that felt like nothing. Four beige walls. Basic white bedding. A dresser from a big-box store and a lamp that flickered.

And then you watched Belly walk into that room at the Cousins Beach house — with the blue botanical wallpaper, the white iron bed frame, the rattan accents, the little trinket bowls on the nightstand — and something shifted in you.

That's what a bedroom is supposed to feel like.

Warm. Nostalgic. Like salt air and a really good summer. Like falling in love with someone you've known your whole life. Like you finally figured out who you are.

The problem is, most people scroll past a thousand Pinterest pins and still don't know what to actually buy or where to start. They know the vibe they want. They just can't get there.

That changes right now.

Here's exactly how to make your room feel like Belly's bedroom at the Cousins Beach house — from the walls to the bedding, to the tiny details that tie the whole thing together. These are all real pieces, all Amazon-shoppable, and most of them are under $50.

💛 Pro Tip: The secret to nailing Belly's room isn't one statement piece. It's layers. Start with the wallpaper, get the bedding right, add rattan textures and vintage accents last. Build it like a story.

The Summer I Turned Pretty Bedroom Ideas: Blue & White Coastal Aesthetic — Start With the Walls

1. Peel-and-Stick Blue Botanical Wallpaper

This is the move. Belly's iconic bedroom wallpaper — blue botanicals on white — is what sets the entire TSITP aesthetic apart from a regular coastal room. It's layered, romantic, and it immediately signals "dreamy beach house."

You don't need to paint or hire anyone. Shop blue and white peel-and-stick coastal wallpaper on Amazon →

Why it works: It creates an instant backdrop that makes even basic white furniture look intentional and styled.

Tips to nail it:

Do a feature wall behind your bed — not all four walls
Pair with white walls on the other sides to keep the room feeling airy
Look for watercolor florals, boat prints, seagull patterns, or leaf botanicals for max TSITP energy

2. Blue and White Floral Quilt Bedding Set

If there's one piece that's going to make your room look unmistakably TSITP, it's the bedding. Belly's bed was done in blue and white floral — a daisy or wildflower quilt that felt romantic without being overdone.

Shop blue floral quilt sets on Amazon →

Why it works: Blue and white is the coastal color pairing that never looks cheap. It works in a teen bedroom, a dorm room, or a grown woman's master suite.

Tips:

Look for a reversible daisy or wildflower print
Layer a white ruffle duvet underneath for that coastal granddaughter bed-stacking effect
Add mismatched floral pillowcases for a collected, lived-in feel

3. White Iron or Slipcovered Bed Frame

Belly's bed frame at the Cousins house was a white iron or panel-style frame — the kind that looks like it's been in a beach house for 40 years and only gotten prettier. It's the anchor of the whole room.

Shop white coastal bed frames on Amazon →

Why it works: White frames bounce light, make the room feel larger, and pair with everything in the TSITP palette.

Before You Start: Measure your room before ordering your bed frame. The TSITP aesthetic works best when there's breathing room — don't overcrowd.

4. Lime Green or Sage Green Bedside Cabinets

This is the detail that makes Belly's room hers. While the bedding and wallpaper are classic blue and white, her lime green bedside cabinets add a pop of unexpected color — and it works because it's grounded by all that white and blue.

Shop colorful rattan or wood nightstands on Amazon →

Why it works: One unexpected color accent is what separates a decorated room from a designed room.

5. Seashell and Nautical Wall Art Prints

Belly's room had subtle nautical print art — small shell prints, boat illustrations, nothing too theme-park. The key is understated.

Tips:

Frame shell prints in simple white or gold frames
Create a mini gallery wall beside your bed — nothing needs to match perfectly
Mix matte paper prints with small ceramic coastal pieces

6. Blue and White Ceramic Trinket Bowl

This is a detail most people miss — but it's everywhere in Belly's room. A small blue and white ceramic bowl on the nightstand for jewelry, hair ties, whatever. It's the most affordable and most effective way to add the TSITP touch.

7. Mini Gold Picture Frames (Gallery Wall)

Belly's room had a cluster of tiny gold frames on her wall — empty or with simple photos. This is one of those details that screams "thoughtfully decorated" instead of "thrown together."

Tips:

Mix rectangular and oval frames for variety
You can leave them empty — the frames themselves are the decor
Cluster them in groups of 3-5 on a blank wall section

8. Daisy Print Pillowcases

11. Rattan or Woven Texture Accents

Rattan is the texture of the TSITP aesthetic. It's what makes a beach house feel intentional instead of just sandy. Rattan nightstands, woven baskets for blankets, cane accent chairs — all of it.

What You Need:

One rattan nightstand or side table
A woven seagrass basket for throw blankets
Optional: a rattan mirror above your dresser

12. Lantern String Lights Above the Bed

This detail appeared in Belly's dorm room in season three — little decorative lantern string lights draped above the headboard. They add a beachy, festival energy that's cozy and romantic at the same time.

13. Gold Floral Wall Hook

Belly's room had a gold floral metal wall hook near her armoire area — and it's one of those small details that makes a room look pulled together. Hang a sun hat, a linen tote, or a robe.

14. Slipcovered or Upholstered Bench at Bed Foot

The Fisher house had layered, collected-over-time furniture energy. A linen or upholstered bench at the foot of your bed instantly elevates the whole setup.

15. Hydrangea or Eucalyptus Dried/Faux Floral Arrangement

The Summer I Turned Pretty Bedroom Aesthetic — Belly's Room Makeover Secrets

Here's what nobody tells you when you're trying to recreate a TV show bedroom:

The set designers didn't just pick pretty things. They picked things that told a story.

Belly's room isn't just coastal. It's coastal with a teenage girl's personality layered over it. The vintage gold frames mix with the modern lime green cabinets. The classic floral quilt lives next to a plush polar bear. The blue botanical wallpaper is serious and romantic — but the daisy pillowcases are playful and young.

That tension is what makes it feel real.

So here's the secret to nailing the full TSITP bedroom aesthetic:

Mix old and new. Mix serious and playful. Mix polished and personal.

16. Blue and White Coastal Color Palette — Everywhere

Navy, sky blue, cream, white. These four colors make up the core TSITP palette. Use them on your walls, bedding, accents, and decor.

17. Grandmillennial Pattern Mixing

Florals on the quilt. Botanicals on the wallpaper. Stripes on a throw pillow. In the TSITP world, patterns mix — they just stay in the same color family.

18. Vintage-Inspired Dresser With Brass Hardware

Swap out plain hardware for brass or gold pulls. That's it. That one swap takes a basic dresser into the TSITP universe instantly.

Shop brass dresser hardware pulls on Amazon →

19. Coastal Grandmother Floor Lamp

Simple, warm-toned, floor lamp. Nothing extravagant. Belly's dorm room had a basic floor lamp — and it worked because it was functional and soft.

Shop coastal bedroom floor lamps on Amazon →

20. Linen Curtains in White or Cream

Sheer white linen curtains let the light pour in soft and hazy — the exact quality of light you see in every TSITP scene. They make any room feel like it's by the ocean.

Shop sheer white linen curtains on Amazon →

21. Coquette Blue Throw Blanket

Layer a soft blue throw at the foot of the bed or over the back of a chair. Textured knit or waffle-weave fabrics work best.

22. Stack of Aesthetic Coffee Table Books

Belly is a book girl. Stack two or three aesthetically-covered books on your nightstand. Look for titles about coastal living, fashion photography, or vintage romance.

Shop aesthetic coffee table books coastal on Amazon →

23. Shell or Rope Textured Mirror

A round mirror framed in rope, shells, or driftwood on your bedroom wall gives that Cousins Beach house energy without being kitschy.

24. Wicker or Rattan Storage Basket

Seagrass baskets for magazines, blankets, or books. One large basket in the corner of your room does more for the coastal vibe than five other decor pieces combined.

25. Pressed Floral or Botanical Art

Framed pressed botanicals or watercolor floral prints in white frames — the kind you'd find in a seaside cottage. These are perfect filler art for gallery walls.
