Fit Tips:
- Chest Measurement: The chest circumference listed is the garment measurement. For comfortable wear, ensure there's adequate ease (typically 4-6 inches) over your actual bust measurement.
- Wide Waist Design: The wide waist construction means this dress doesn't cinch at the waistline, creating a flowing, relaxed silhouette that's comfortable for all-day wear.
- Split Detail: The side split provides ease of movement and adds visual interest. The split allows for comfortable walking and sitting while maintaining modest coverage.
- Extended Sizes: Sizes 4XL and 5XL are available. For specific measurements on these sizes, please contact our customer service team who can provide detailed dimensions.
- Length Guidance: For specific dress length measurements for your size, please contact customer service. Length will vary by size and is designed to provide appropriate coverage.
- Sleeveless Fit: The sleeveless design requires proper shoulder and armhole fit. If you have broader shoulders, consider sizing up for comfort.
- Measurement Variance: Please allow 1-2 cm (approximately 0.5-1 inch) differences due to manual measurement.
Features & Fabric
- Key Features: Sleeveless design keeps you cool during warm weather while showing off toned arms. Classic round neckline offers timeless, flattering styling. Modern side split detail adds movement, contemporary edge, and ease of mobility. Wide waist construction provides comfortable, non-restrictive fit without elastic or tight waistbands. Solid color design makes styling effortless and creates a versatile foundation for accessories.
- Material Composition: 100% polyester — a practical choice for summer dresses due to its durability, wrinkle resistance, quick-drying properties, and easy care
- Fabric Feel: Lightweight polyester with a smooth, comfortable texture perfect for warm-weather wear. The fabric drapes nicely creating an elegant flow without clinging to the body. Quick-drying properties mean it won't stay damp from perspiration in hot weather. The material resists wrinkles, helping you maintain a fresh appearance throughout the day.
- Split Detail: Side split adds contemporary style and functional benefits — it creates visual interest, allows for easier movement when walking, and adds a subtle touch of sophistication to the simple silhouette.
- Stretch: Polyester fabric typically offers some natural give and flexibility for comfortable movement, though this is designed as a flowing dress rather than a stretch-fit style
- Opacity: Polyester fabric provides good coverage, though lighter colors (white, yellow, light purple, sky blue) may require nude or color-matched undergarments to prevent show-through
- Color Options: Ten beautiful solid colors to choose from — neutral khaki, soft light purple, cheerful yellow, fresh sky blue, classic white, timeless black, rich dark green, vibrant purplish red, versatile gray, and serene light green. Each offers the same flattering silhouette in different color palettes.
- Care Instructions: Machine wash cold with like colors using a gentle cycle. Polyester is naturally wrinkle-resistant. Tumble dry on low heat or hang to dry. Remove promptly to minimize any creasing. Do not bleach. Iron on low heat if needed. The easy-care nature makes this perfect for vacation and frequent summer wear. Imported.
How to Style
This sleeveless dress is your effortless summer essential that works for everything from beach vacations to backyard barbecues. The solid color makes it incredibly easy to style while the split detail adds just enough interest to keep it from being boring.

Complete Outfit Ideas
- Beach Vacation Casual: Wear this dress with flat sandals or espadrilles and a wide-brim straw hat for perfect beach town style. Add oversized sunglasses and a woven tote bag. The sleeveless design and side split make it comfortable for hot weather exploring. Perfect for beachside cafes, resort activities, or walking along the boardwalk. Layer with a denim jacket or kimono for evening.
- Summer Weekend Brunch: Style with strappy flat sandals or wedges and add a statement necklace that complements the round neckline. Carry a crossbody bag and add simple hoop earrings. The solid color makes accessorizing easy — you can go bold with jewelry since the dress provides a clean canvas. Perfect for brunch dates, farmers' markets, or casual lunch with friends.
- Elevated Casual Evening: Dress it up with heeled sandals or block-heel mules and add statement earrings. The side split adds movement when you walk, creating an elegant effect. Carry a clutch and add a lightweight blazer or structured cardigan if needed. This works for casual dinner dates, outdoor summer concerts, or evening gatherings where you want to look polished but not overdressed.
- Pool or Resort Wear: Style as a swimsuit cover-up by wearing it over your bikini or one-piece. Add flip-flops or slide sandals and oversized sunglasses. The wide waist and sleeveless design make it easy to slip on over damp swimwear. Perfect for walking from the pool to lunch, or lounging poolside with a book. The polyester fabric dries quickly if it gets splashed.
- Layered Transitional Look: As temperatures cool in the evening or for air-conditioned spaces, layer with a fitted long-sleeve tee underneath for coverage. Add sneakers or ankle boots and a crossbody bag. This creates a creative, layered look that extends the dress's wearability beyond just hot summer days. The sleeveless dress layers beautifully over fitted pieces.
Styling Q&A
- Q: How long does shipping take?
- A: This item qualifies for standard delivery and typically arrives in 7-12 business days within the USA.
- Q: How high does the side split go? Is it too revealing?
- A: While the exact split height isn't specified in the measurements, side splits on dresses like this typically hit mid-thigh to just above the knee, providing movement and style without being overly revealing. The split is designed to add visual interest and ease of walking while maintaining modest coverage. If you're concerned, you can always wear bike shorts or slip shorts underneath for additional coverage and peace of mind.
- Q: What type of bra should I wear with this sleeveless dress?
- A: The round neckline and sleeveless design work with several bra options. A regular bra with straps that don't extend too far toward your shoulders works for most people. Strapless bras or bralettes are great if you want no visible straps. For lighter colors, choose a nude bra that matches your skin tone rather than white. The key is ensuring your bra doesn't show at the armholes or neckline.
- Q: I'm usually a US size large. What size should I order?
- A: Since this follows Asian sizing (which runs 1-2 sizes smaller than US sizing), we recommend ordering at least a size XL or 2XL if you're typically a US large. Check the chest circumference in the size chart and compare it to a dress that fits you well. Make sure to account for the needed ease over your bust measurement. When in doubt, size up for comfort.
- Q: Which color is most versatile?
- A: Black is the most universally versatile — it works for any occasion, pairs with any accessories, and is flattering on all skin tones. White is a classic summer choice but requires careful undergarment selection. Khaki and gray are excellent neutrals that work across seasons. Sky blue and light green are perfect for summer and vacation. Choose based on what colors you wear most and what coordinates with your existing wardrobe and accessories.
- Q: Can I dress this up for semi-formal events, or is it too casual?
- A: This dress is best suited for casual to smart-casual occasions rather than semi-formal events. However, you can elevate it significantly with styling — add heels, statement jewelry, a structured blazer, and an elegant clutch. It works for casual summer weddings (as a guest, not too formal), garden parties, or upscale brunch. For truly semi-formal events, you'd want something more structured or embellished.
- Q: How do I care for this dress to keep it looking fresh?
- A: The polyester fabric makes care easy. Wash in cold water on gentle cycle after each wear to keep it fresh. Lighter colors may show stains more easily, so treat any spots promptly. Hang to dry or tumble dry on low — polyester dries quickly. The wrinkle-resistant nature means you can pack it for travel without worry. For stubborn wrinkles, steam or iron on low heat. This dress is designed for frequent wear and easy maintenance.
