Frequently Asked Questions
Everything you need to know about our high-performance athletic apparel.
How do I choose the right size in OISELLE gear?
We recommend checking our detailed Size Guide located on each product page. Our apparel is designed for a performance fit; if you prefer a looser feel for your runs, we suggest sizing up.
What is your return policy for performance apparel?
We offer a 30-day return window for all unwashed and unworn items with original tags attached. Please note that final sale items are not eligible for return or exchange.
How should I care for my technical running fabrics?
To maintain the integrity of our technical fabrics, we recommend machine washing on a cold, gentle cycle with similar colors and hanging to dry. Avoid fabric softeners and bleach.
Do you offer international shipping?
Yes, we ship to most countries worldwide. Shipping costs and delivery timelines are calculated at checkout based on your specific location and selected service level.
What payment methods do you accept?
We accept all major credit cards (Visa, Mastercard, American Express, Discover), as well as digital payment options like PayPal, Apple Pay, and interest-free installment plans through Afterpay.
