Frequently Asked Questions
Everything parents ask, in one gentle place.
How long will my order take to arrive?+
We dispatch every order within 1-2 business days. Standard delivery within India typically arrives in 3-5 business days; express delivery (1-2 days) is available at checkout. You'll get a tracking link by email and SMS the moment your little one's parcel is on its way.
What is your returns and exchanges policy?+
Kids grow fast, so we keep it easy. Return or exchange any unworn item with tags within 15 days of delivery. Size exchanges are always free, and we send a prepaid label for your first return on every order. Just reach out to our support team to start.
How do I choose the right size for my child?+
Each product page includes a detailed size chart with age, height and chest measurements, and our pieces are cut with room to grow. If your child is between sizes, size up. Still unsure? Message us their height and age and we'll recommend the perfect fit. See the full size guide.
What fabrics do you use, and are they safe for sensitive skin?+
Every SUMIX garment is 100% GOTS-certified organic cotton, grown without pesticides or harmful chemicals. We use OEKO-TEX certified non-toxic dyes and avoid rough seams, so even the most sensitive skin stays happy. All snaps are securely fastened and tested for little ones.
How should I wash and care for my SUMIX clothes?+
Machine wash cold (30°C) with similar colours using a gentle, fragrance-free detergent. Tumble dry low or line dry in shade, and skip bleach and softener. See the full care guide — our organic cotton only gets softer with every wash.
How does the SUMIX rewards programme work?+
