Frequently Asked Questions
Everything you need to know about OISELLE athletic apparel.
How do I choose the right size for my running gear?
We recommend referring to our comprehensive Size Guide located on each product page. Our apparel is designed for a performance fit; if you prefer a looser feel, 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 for hygiene reasons, underwear and certain base layers are final sale.
How long will it take for my order to ship?
Standard shipping typically takes 3-7 business days. Once your order leaves our warehouse, you will receive a tracking number via email to monitor your delivery status.
Do you offer international shipping?
Yes, we ship to most countries worldwide. International shipping rates and delivery timelines are calculated at checkout based on your specific location and local customs regulations.
How should I care for my OISELLE technical fabrics?
To preserve the technical properties of our fabrics, we recommend machine washing in cold water with like colors and hanging to dry. Avoid using fabric softeners or bleach.
Can I change or cancel my order after it has been placed?
Because we strive to process orders as quickly as possible, we have a very limited window for changes. Please contact our customer service team immediately if you need to modify your order.
