Halter Vest & Wide-Leg Pants

Structured on top, relaxed on the bottom. The halter vest brings a tailored edge, balanced by loose white pants and chunky sneakers. A red bag and layered gold jewelry add a fun, polished touch.
Striped Shirt & White Shorts

An oversized red-striped button-down adds a pop over a classic white tank and high-rise shorts. Finished with tan slides, a brown belt, and a neutral tote for that easy, pulled-together look.
Black Tee & White Jeans

Simple contrast, always a win. A cropped black tee pairs effortlessly with straight-leg white jeans. Finished off with black slides and a straw-accented bag for an easy neutral balance.
Cream Vest & Linen Shorts

Crisp and neutral. A structured vest meets high-waisted linen shorts for a look that feels sharp but relaxed. Black strappy heels and a mini bag add just the right contrast.
Floral Midi Dress & Baseball Cap

Puffed sleeves and soft florals bring a romantic feel, while the black cap and sunglasses add contrast. Finished off with flat brown sandals and a shoulder bag—easy, cool, and unfussy.
Denim Vest & Flowy Skirt

Cropped denim on top, breezy volume on the bottom. A denim vest pairs perfectly with a white maxi skirt for a mix of structure and movement. Add a wrap belt to define the waist and black boots to ground the look with a bit of edge.
Black Tank Top & White Jeans

A fitted black tank keeps it sleek up top, while wide-leg white jeans add contrast and ease. Black flip-flops keep the vibe laid-back, and a slouchy beige bag adds a soft, neutral touch.
Polka Dot Dress & Mary Jane Flats

A fitted polka dot slip dress brings that timeless, easy summer feel. White Mary Jane flats keep the look sweet and simple, while a structured red shoulder bag adds a fun color pop.
Tank Top & Maxi Skirt

A white tank keeps it fitted and simple, while the flowy cream maxi skirt adds a soft, easy silhouette. The unbuttoned blue shirt works as a light layer, and black flip-flops finish it off with a casual touch.
Cream Vest & Wide-Leg Trousers

A structured cream vest meets relaxed tan wide-leg trousers for a look that’s polished but easy. Simple slides and a straw tote keep it casual, while gold jewelry adds just the right amount of shine.
Button-Up Shirt & White Mini Skirt

Love how the crisp blue shirt adds structure to an otherwise simple base. A white tank tucked into a belted mini skirt keeps things light and clean, while the black accessories—heeled sandals, clutch, and belt—tie it all together.
Ruffle Blouse & Flowy Skirt

Lightweight and effortless. A white tie-front blouse with ruffle sleeves pairs perfectly with a breezy yellow maxi skirt. Add simple flip-flops and a straw tote to keep it relaxed and vacation-ready.
White Tee & Satin Midi Skirt

Easy mix of casual and sleek. A fitted white tee balances the shine of a black satin skirt with lace trim. Round it out with ballet flats, bold jewelry, and a black shoulder bag for a polished day look.
Striped Shirt & Matching Shorts

Matching sets always make getting dressed easier. This blue-and-white striped button-down with coordinating shorts feels relaxed but put-together. Add tan slides, a straw tote, and you’re good for anything from errands to a bakery stop.
Halter Polka Dot Dress & Kitten Heels

Flirty but minimal. The halter neckline and flared silhouette give this polka dot mini a playful edge. Paired with black kitten heels, a tiny top-handle bag, and bold sunglasses for a chic, retro-inspired finish.
Linen Dress & Wide-Leg Pants

Layering a sleeveless button-front linen dress over loose white pants adds dimension without heat. Black sandals, a structured bag, and chunky gold hoops bring in just enough contrast to keep it sharp.
Striped Tee & White Mini Skirt

Easy and sporty. A fitted striped tee paired with a white mini skirt creates a clean, casual look. Platform flip-flops and a black tote keep it simple but bold.
Eyelet Set & White Flats

Matching sets always win. This cream eyelet two-piece feels fresh and feminine with its sheer cutout details and wide-leg silhouette. Finished with white flats and a big smile—because ice cream is a summer accessory too.
Sleeveless Top & Textured Maxi Skirt

Sleek up top, breezy on the bottom. A fitted ivory tank contrasts nicely with a flowy, black textured maxi skirt. Paired with flip-flops and oversized sunnies for that effortless summer-in-the-city feel.
Blue Shirt & Denim Shorts

Laid-back layers done right. A loose blue button-down over a white tank keeps it effortless, while long denim shorts and flip-flops make it ideal for warm, no-fuss days. Simple, classic, and wearable on repeat.
White Tee & Wide-Leg Jeans

Clean lines and strong details. An oversized white tee tucked into high-rise wide-leg jeans sets the base, while a black belt, chunky sandals, and gold jewelry polish it off. The mini straw bag adds just enough texture to break up the monochrome.
White Button-Down & Wide-Leg Trousers

Effortlessly sharp. A crisp white shirt layered over a fitted tank adds structure, while charcoal wide-leg trousers keep the look clean and refined. Black sandals, a belt, and classic sunglasses pull it all together without trying too hard.
Cherry Tee & Gingham Capris

Playful with a retro twist. A cropped graphic tee adds charm, paired with red gingham capris for that classic summer vibe. Finished with black Mary Janes and a mini top-handle bag to keep it sweet but structured.
Tailored Vest & Flared Jeans

Soft structure meets casual denim. A beige vest with button detailing adds shape up top, balanced by light-wash flared jeans. White sneakers and a black shoulder bag keep the look grounded and easy to wear all day.
Tie-Front Top & Mini Skirt

Light and sporty. A sleeveless tie-front top keeps it breezy, styled with a black mini skirt and classic white sneakers. Sunglasses and a black shoulder bag give it a cool, casual finish.
