Frequently Asked Questions
Everything you need to know about your Nostrum shopping experience.
How do I determine my correct size?
Each product page features a detailed sizing guide with specific measurements. Because our silhouettes range from tailored to oversized, we recommend checking the 'Fit Notes' section for individual garment advice.
What is your shipping policy for international orders?
Nostrum ships worldwide. Orders are typically processed within 1-2 business days. International delivery times vary by location, generally arriving within 7-14 business days via our premium courier partners.
What is your return and exchange window?
We offer a 30-day return policy for all unworn items with original tags attached. To initiate a return or exchange, please visit our online Return Portal to generate a prepaid shipping label.
How should I care for my Nostrum garments?
To ensure longevity, we recommend following the specific care instructions on the internal garment label. Most of our high-quality fabrics benefit from cold washing and air drying to maintain their shape and texture.
Which payment methods do you accept?
We accept all major credit cards (Visa, Mastercard, American Express), PayPal, Apple Pay, and Google Pay. We also offer flexible 'Buy Now, Pay Later' options through Klarna and Afterpay.
Are your products ethically manufactured?
Sustainability and ethics are core to Nostrum. We partner exclusively with certified factories that ensure fair wages, safe working conditions, and utilize eco-friendly production methods wherever possible.
