Features & Fabric
- Key Features: Long sleeve button-down romper with shirt-dress styling; functional button-front closure from neckline to waist; attached mid-thigh shorts for all-in-one outfit; lace-up detail accent for trendy appeal; collar neckline for polished sophistication; available in extended sizes S-5XL
- Material Composition: Spandex-blend fabric—a synthetic elastic fiber known for exceptional stretch, recovery, and comfort. The high spandex content creates a form-fitting silhouette that moves with your body
- Fabric Feel: Smooth, soft texture with a slight sheen that catches light beautifully. The stretchy material feels comfortable against skin and provides a body-hugging fit without restriction. Lightweight construction keeps you cool in warm weather while the long sleeves offer sun protection and coverage. The fabric has memory and returns to its original shape after wear and washing.
- Stretch: High stretch—the spandex-blend composition allows the romper to expand comfortably across the bust, waist, and hips, then return to shape. This stretch accommodates movement, sitting, and various body types effortlessly
- Opacity: The fabric thickness provides good opacity, though we recommend nude-tone undergarments for lighter colors to ensure complete coverage and confidence
- Design Details: Functional button-front allows styling versatility; collar neckline adds shirt-dress sophistication; long sleeves with fitted cuffs; lace-up accent detail (placement may vary); defined waist seam transitions to attached shorts; mid-thigh shorts length with comfortable leg openings
- Versatile Styling: The button-front design lets you customize your look—wear fully buttoned for a polished, modest aesthetic or leave the top few buttons undone for a casual, relaxed vibe. Roll up sleeves for warmer days or keep them down for cooler evenings.
- Care Instructions: Hand wash cold with mild detergent to preserve the elasticity and shape of the spandex fabric. Avoid harsh chemicals or bleach which can damage stretch fibers. Gently squeeze out excess water without wringing. Hang to dry or lay flat on a clean towel away from direct heat or sunlight. Do not iron directly on high heat. Store folded or hung to prevent stretching. Imported.

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: What size should I order if I typically wear a US Small?
- A: Since this follows Asian sizing which runs 1-2 sizes smaller, we recommend ordering a size M or L if you typically wear a US Small. The stretchy spandex fabric is forgiving, but sizing up ensures comfort across the bust and hips. Always measure and compare to our size chart for the most accurate fit.
- Q: Is this actually a romper or a jumpsuit?
- A: This is a romper! It features shorts (approximately 20-23 inches in length) rather than full-length pants. The shorts hit at mid-thigh, offering playful, comfortable coverage perfect for warm weather while maintaining a sophisticated shirt-dress aesthetic on top.
- Q: What should I wear underneath this romper?
- A: We recommend seamless, nude-tone undergarments to avoid visible lines given the stretchy, fitted fabric. A strapless or regular bra works depending on your comfort level. For lighter colors, nude undergarments ensure complete opacity and confidence.
- Q: Can I wear this in slightly cooler weather?
- A: Absolutely! The long sleeves make this romper perfect for transitional seasons. Layer with tights or leggings underneath if you want extra coverage in cooler temperatures. Add a denim jacket, blazer, or cardigan on top. Swap sandals for ankle boots, and you have a cute fall outfit.
- Q: How do the buttons work—are they functional or decorative?
- A: The buttons are functional, allowing you to customize your neckline and overall look. Wear fully buttoned for a polished, modest appearance, or leave the top 1-2 buttons undone for a more casual, relaxed vibe. This versatility makes the romper work for multiple occasions.
- Q: Will this romper ride up when I sit down?
- A: Like most rompers and shorts, there may be slight riding up when sitting, but the mid-thigh length provides reasonable coverage. The stretchy spandex material moves with you and doesn't restrict movement. Simply adjust when you stand up if needed—this is normal for fitted romper styles.
