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?
- A: This romper uses Asian sizing and has a slim-fit design. We strongly recommend ordering at least one size up from your normal US size. If you typically wear a US Medium, order Large or XL for a comfortable athletic fit that's not too tight.
- Q: Is this tight enough to stay in place during workouts?
- A: Yes! The slim fit and medium elastic fabric are designed to stay in place during movement. The form-fitting design prevents shifting during exercises while the stretch allows full range of motion.
- Q: Can I wear this for different types of workouts?
- A: Absolutely! This versatile romper works for yoga, pilates, gym workouts, running, cycling, and general fitness activities. The stretchy fabric and secure fit make it suitable for various movements.
- Q: How are the sleeves—do they restrict movement?
- A: The long sleeves are made from the same stretchy material and move with you. They provide coverage without restricting arm movement during exercises like lifting, stretching, or reaching.
- Q: Is this see-through or does it provide good coverage?
- A: The medium-weight acrylic fabric provides good coverage when properly sized. However, as with any athletic wear, we recommend doing a squat test and wearing appropriate undergarments for your comfort level.
- Q: How short are the shorts?
- A: The shorts hit at mid-thigh length—not too short, not too long. They're designed to stay in place during workouts while providing freedom of movement for your legs.
- Q: Can I wear this outside the gym?
- A: Yes! The sleek design makes it perfect for athleisure styling. Layer with jackets, hoodies, or wear as-is for a sporty casual look for errands, coffee runs, or casual outings.
- Q: Does the fabric wick moisture?
- A: Acrylic fabric has some moisture-wicking properties and dries relatively quickly. While it's not technical performance fabric, it's suitable for moderate-intensity workouts and everyday active wear.
- Q: Will this pill or lose shape over time?
- A: Acrylic fabric is generally resistant to pilling and maintains its shape well. Follow care instructions (wash cold, hang or low heat dry) to preserve the fabric's elasticity and appearance.
