Belly’s style is a mix of sporty casual and feminine elegance with a touch of coastal grand daughter. In season one she is just finding her sense of style as she grows comfortable with her new found social acceptance and realizes that she is desirable to potential romantic prospects. By season 2, she has established her style as casual, sporty, feminine, and cool.

1. Tees & Denim Cutoffs

Belly often starts her day in T‑shirts and denim cutoffs—the ultimate representation of laid‑back beach life. Jessica Flaherty, the costume designer, explains: “We wanted pieces Belly could just live in—comfy, easy, nothing too polished.” These basics feel lived‑in and real, making her relatable, not curated.

Or this pair of cutoffs that are a casual classic.

2. Playful Prints

Tiny daisies and gingham appear as soon as Belly starts exploring her independence. Whether it’s the small floral on a sundress or the gingham pattern on her picnic-ready top, these prints feel nostalgic and young—perfect for lazy afternoons chasing waves or boardwalking with friends.

Or if you dresses aren’t your thing and you’d rather have a top, try this cute gingham crop top that laces up in the back:

3. Embrace soft pastels & florals

Costume designer Flaherty said: “Bright purple might be the color of the summer, but we’re doing pastel blues… soft and untouched by the harsh realities of high school.” These hues—pinks, blues, gentle floral motifs—echo the innocence of summer and hint at Belly’s emotional journey. They’re romantic, sweet, and quietly optimistic.

4. Casual Swimwear Layering

Belly’s style includes swimsuits peeking out from denim shorts or crochet crop tops. It’s beachwear that doesn’t scream “resort” but whispers “I live here.” It’s efficient, easy, and hints at spontaneity—one minute she’s at the water, the next at an impromptu bonfire.

Or grab this minimalist version:

5. Spaghetti‑Strap Tops

When Belly steps it up—say, for a summer party—she does so softly. Flowy tops or minimalist dresses. At the debutante ball, Belly wears a simple white gown with pearls and minimal embellishments. Jenny Han says the scene “symbolizes Belly’s transition to adulthood”—a deliberate choice to show beauty in simplicity: mature, not flashy.

6. Babydoll Dresses

Think lilac mini-dresses, pastel yellow sundresses, or soft white babydolls that have movement and sweetness without being overdone. Flaherty wanted timeless pieces that don’t look “sharp and bright like high school shows”—just “soft, untouched, dreamy pastels” inspired by decades past.

7. Stripes

Belly often wears horizontal striped tops as they are practically a rite of passage for a coastal coming-of-age story. They evoke all the summer clichés we love: Nautical themes, Beach towels and umbrellas, Classic Americana style. Stripes, especially the kind she wears—soft, muted, often horizontal—symbolize structure and simplicity. They remind us that beneath the emotional messiness, she’s still grounded. It’s subtle, but powerful. Lola Tung (who plays Belly) even said in an interview “Her wardrobe has a lot of charm to it—like, she doesn’t try to be perfect. Even when she’s trying to be noticed, it’s still very her.”

8. Go More Daring like Belly Season 2:

In Season 1, Belly’s outfits were soft, girly, and youthful with the gingham dresses, daisy motif, and pastel cardigans. But by Season 2, especially at parties, her clothes start to feel a little more daring. Her hems are shorter, her tops are tighter, and her makeup becomes more defined.This isn’t about trying to look “older” or “sexier” in the stereotypical sense—it’s about Belly stepping into herself. She’s still awkward and sensitive and smart, but she’s figuring out who she is with and without the boys who’ve known her since she was 10. As Tung said in an interview with Teen Vogue: “She’s experimenting with what it means to be seen—not just as the little sister anymore, but as someone who’s growing up and maybe wants to be noticed in a different way.”

9. Chunky Knit Sweaters

In the fall and winter, Belly swaps her slinky sundresses for chunky knits. Think slightly oversized cable-knit sweaters in soft colors like oatmeal, rose, and seafoam. They’re usually layered over a plain tee or a thermal top. The look is practical for school, but still sweet and very “Belly”—especially when paired with a dainty necklace.

10. Muted Color Palette

Gone are the pastels of summer—in winter, Belly’s wardrobe shifts to earthy tones: rust, forest green, ivory, navy, and soft browns. These shades echo the seasonal change and her emotional arc as things get more complicated with Conrad, Jeremiah, and the rest of her world. “We pulled her color palette way back during the school year—everything was a little dimmer,” Flaherty shared in a behind-the-scenes post. “It mirrors her inner world shifting after summer ends.”

In the colder months and school-year scenes, Belly’s wardrobe becomes more introspective—less sun-drenched and more grounded. You’ll notice her outfits are full of layers, softness, and practicality, but never lose the romantic quality that defines her character.

It’s not about chasing trends—it’s about growing up and learning who you are when no one’s watching.

In The Summer I Turned Pretty Season 3, Belly Conklin’s wardrobe reflects her transition from carefree teen to a more self-assured young woman, blending nostalgic charm with modern sophistication. Costume designer Jessica Flaherty described the show’s fashion as “classic and dreamy and timeless and a little bit vintage, but also cool and hip,” capturing a mood that feels effortlessly stylish yet deeply tied to Belly’s emotional growth.

Perhaps the most talked-about fashion moment was Belly’s so-called “plain” wedding dress, actually a sleek Victoria Beckham slip gown famously worn by Kim Kardashian, which underscored the character’s evolving sense of understated elegance. Each outfit in Season 3 works as more than just clothing—it’s a visual cue to Belly’s coming-of-age journey and the shifting dynamics around her.
