Materials & care
Materials & care
Soft, Safe & Sustainable
At Estella, we believe in high-quality, baby-friendly materials. Our clothes, toys, and accessories are made from 100% certified organic cotton, ensuring softness, breathability, and safety for delicate skin. Loulou Lollipop swaddles and select items feature other natural fibers, always chosen with comfort and sustainability in mind.
Easy Care for Busy Parents
We make life simpler—everything in our collection, including our plush toys, is machine washable for easy cleanup.
Clothing & Toys: Machine wash cold, lay flat to dry. No dry cleaning necessary.
Swaddles & Blankets: Machine wash cold, tumble dry low or lay flat to dry.
Books: Wipe clean with a dry or slightly damp cloth as needed.
Designed for everyday messes and cuddles, our products hold up beautifully wash after wash.

Fast & Reliable Shipping
Order by 12pm ET, Monday–Friday and your gift ships the same day. Free standard shipping on US orders $75+, $8 under $75. Express shipping (2 business days) available at checkout.
Gift-Ready, Never Prices
No price tags on any product. Every order includes a gift receipt that lists items and quantities, never prices. Add a free gift message in your cart and we print it on the gift receipt. Gift boxing is complimentary on orders $175+, or $8 under $175. Our gift baskets and the rattan diaper caddy arrive as they are — the basket is the presentation, so they don't come in an additional gift box.
Hassle-Free Exchanges & Returns
We want you (or your gift recipient) to love every Estella purchase! You may return or exchange your item within 30 days for a full refund—no questions asked.
To be eligible for a return or exchange, items must be:
✅ In new, unused condition
✅ Accompanied by a copy of the receipt
✅ Regular-priced items only. Sale items are final sale.

Are your clothes sized smaller, larger or average?
Our clothes are sized smaller than average, and we recommend buying 1 size larger. For example, if the baby is 0-3 months old, we recommend buying a 3-6 month size. See our size chart for more details.
Do your receipts include prices?
Since most of our orders are gifts, we never include prices in our receipts. Gift receipts list items purchased & quantities never the prices.
Can I include a gift message?
Yes! You may add a gift message for free. On the shopping cart, you can type in a gift message, and we will include it with the gift receipt.
Do you offer free gift wrapping?
Yes! Gift boxing is complimentary on orders $175+. For orders under $175, you can add Estella gift boxing for $8 and we'll wrap and box the gift for you. Our gift baskets and the rattan diaper caddy are the exception — the basket is the presentation, so they ship as they are rather than inside a gift box.
Do you have a store front?
No, we are fully online. We do sell through many boutiques nationwide, but our full line is exclusively available online.
