If you thought the Coastal Granddaughter aesthetic was fading out with the rise of edgier Y2K throwbacks and streetwear-infused summer looks, The Summer I Turned Pretty Season 3 is here to remind you otherwise. With flowing fabrics, pastel palettes, nautical stripes, and oversized button-ups styled effortlessly, the TSITP S03 Outfits signal one thing clearly: this soft, breezy trend isn’t going anywhere.
More than a microtrend, Coastal Granddaughter has become a full-fledged style archetype and Season 3 of TSITP doesn’t just revive it, it evolves it. Here’s how the trend still feels fresh in 2025 and what these character outfits reveal about its staying power.
Defining the Coastal Granddaughter Aesthetic (2025 Refresh)
The Coastal Granddaughter look originally found fame on TikTok in 2022, but in 2025, it’s moved beyond a vibe to a lifestyle. Think light knits, white cotton layers, barely-there makeup, and the kind of clothing that whispers “I read Joan Didion by the ocean.”
What makes it still relevant today is how it adapts to modern styling blending comfort with intention. TSITP S03 Outfits captures this perfectly through the wardrobes of Belly, Taylor, Shayla, and even Steven, proving the aesthetic isn’t just reserved for quiet luxury types but anyone craving ease with elegance.
TSITP S03 Outfits: Key Looks That Reinforce the Trend
1. Belly’s Oversized Blue Button-Up and White Shorts Combo
This is Coastal Granddaughter 101: a slightly rumpled, borrowed-from-the-boys button-up paired with clean white shorts. Belly’s beachside walk in this outfit feels relaxed but curated, a hallmark of the trend. The muted palette, loose silhouette, and natural hair complete the look.
2. Taylor’s Cottagecore Sundress with Open-Toe Slides
Taylor dials up the flirt factor, but her floral midi dress, soft curls, and barely-there accessories are firmly rooted in the trend’s romantic side. The dress screams “summer breeze” while still feeling grounded enough for a real-life brunch or beach picnic.
3. Shayla’s Knit Cardigan and Linen Pants Look
Shayla leans into elevated resort wear with this light cardigan layered over a tank and wide-leg pants. There’s structure, but the softness of the knit and color palette keep it deeply aligned with Coastal Granddaughter energy. This outfit feels ideal for early morning walks on the dock or quiet moments watching fireworks.
4. Steven’s Casual Layers and Fisherman Sweater
Yes, the trend is unisex when interpreted thoughtfully. Steven’s use of textured knits and rolled cuffs especially in the boardwalk scenes nods to New England prep with a Gen Z update. His outfits mirror the kind of refined layering seen in collections like the menswear hoodies and textured jackets found at Las Vegas Jacket.
Why TSITP Is the Ultimate Coastal Granddaughter Style Guide
The Summer I Turned Pretty S03 Outfits give this aesthetic fresh relevance because they show that it’s not just about looking beachy it’s about feeling effortless and emotional. The characters are constantly evolving, and so is their wardrobe. Belly’s clothes, in particular, move between innocence and maturity, echoing the romantic-yet-grounded nature of Coastal Granddaughter fashion.
Even the show’s color grading and cinematography lend support: soft lighting, pastel-drenched sets, and seascape backdrops tie into the aesthetic’s themes of introspection, nostalgia, and youthful longing.
Unlike fast-moving fashion fads, the TSITP Outfits Collection doesn’t scream for attention. It invites the viewer in quietly, poetically, and with a sense of calm confidence. This is exactly why the Coastal Granddaughter look endures.
Is the Trend Still Wearable in 2025? Absolutely. Here’s How.
While the original trend emphasized linen everything and minimal accessories, the 2025 version welcomes subtle updates:
Lightweight outerwear like cropped bombers or cotton dusters add depth without overpowering softness
Textured hoodies in soft colors (as seen in brands like Las Vegas Jacket) offer transitional layering for breezy evenings
Muted sneakers or classic loafers replace sandals, bridging the gap between casual and polished
Silk scarves and basket bags remain key accessories for those finishing touches
What TSITP Season 3 does best is reaffirm that dressing with softness and intention will never go out of style. In a world saturated with bold statements and high-volume trends, the Coastal Granddaughter aesthetic offers a return to simplicity a reminder that minimal can still be meaningful.
Final Thought
The characters in TSITP may be navigating complicated relationships, but their wardrobes have never been more clear in their messaging. Coastal Granddaughter is still in, and TSITP S03 proves that it’s not just a passing phase it’s a mood, a memory, and a mirror of who you are when you’re at peace with yourself.
