Frequently Asked Questions
Everything you need to know about your Mermaid Lucia gear.
How do I choose the right size for my athletic wear?
We recommend referring to our detailed Size Guide located on each product page. Our performance fabrics are designed for a compression fit; if you prefer a more relaxed feel, we suggest sizing up.
What is your return policy for sports equipment and apparel?
We offer a 30-day return window for all unworn and unwashed items with original tags attached. Please note that for hygiene reasons, swimwear and undergarments must have the protective liner intact.
How long does shipping take for domestic orders?
Standard domestic shipping typically takes 3-5 business days. You will receive a tracking number via email as soon as your order leaves our warehouse.
Are Mermaid Lucia products sweat-proof and squat-proof?
Yes, all our leggings and activewear are crafted from high-density, moisture-wicking fabrics that ensure full coverage and dryness during high-intensity workouts.
Do you offer international shipping?
We currently ship to over 50 countries worldwide. International delivery times vary by location but generally range between 7-14 business days.
How should I care for my performance gear to ensure longevity?
To maintain fabric elasticity and color, we recommend machine washing in cold water with similar colors and hanging to dry. Avoid using fabric softeners or bleach.
