    LOVE it!

    So thrilled I was able to get my hands on this color. It's absolutely beautiful and very multidimensional. I find that the Crystalline formula has good wear time as well.

    Blue Stardust

    Because this is a darker color, I prefer to start with a base of eyeliner smudged out. It smokes out really easily. The application isn't too difficult and it stays on the lid pretty well. There can be some fallout, so I would suggest applying foundations or concealers last.

    Shimmery Teal Stardust

    Gorgeous color and formula! I love to sweep it under the eye with subtle wings for a fresh-faced pixie look.

    Like Turquoise Stars

    So far, I've had fun putting Caerulum on top of colors like dark purple and navy blue. I look forward to trying this with a more sheer look overall. I love this color!

    Glittery mermaid feels!

    I am obsessed with this color! It looks great paired with so many colors, or just by itself! I've used it like glitter to add dimension, or on its own. Magical shade!

BLACK FRIDAY WEEKEND SALE GUIDE

We are so excited for you to join us. This event is crafted with deep passion and devotion by our small, independent team, and we want every Rituelist to confidently capture the colors they desire most. Explore below to find answers to your every question, or if you would like to learn more, read our complete sale terms and conditions.

THE BASICS

🖤 Our Black Friday Weekend Sale starts at Midnight (12 am) Pacific Time on Friday, 11/28, and ends at 11:59 pm Pacific Time on 12/1: Black Friday through Cyber Monday.

🖤 This is our most exciting event of the year: 20% off sitewide on all full-sized products + up to 5 all-new, limited-edition free gifts with purchase.

🖤 Exclusively on ritueldefille.com. Excludes TikTok Shop, Shop App, or any other platforms or retailers.

🖤 Use code BF20 at checkout for 20% off. You can also use a sale code from your favorite creator; it should also end in "20." Remember, each order can only use one code, so Rituelist Rewards codes cannot be added on top of a sale code.

🖤 Know what's part of the sale. Everything about this event applies exclusively to full-sized, in-stock products. This includes absolutely all full-sized makeup, skincare, brushes and sets thereof that's currently in stock and available for purchase. (Samples, sample sets, gift cards, shipping, parcel protection and taxes are not part of the sale, and do not count toward GWP qualification.)

🖤 The new colors can be yours. We created our new 2025 Black Friday Collection to be gifts for you, but they will also be available for purchase as long as stock lasts.

🖤 Know the stock up limits: This event is for Rituelists, not resellers! To keep things fair and ward off unauthorized bulk ordering, limit three (3) units per specific color/item (SKU). Contact us before ordering if you would like to request large gifts or professional use exceptions. For the 2025 Black Friday GWP Collection: Limit one (1) of each shade free, and limit three (3) of each shade for purchase.

🖤 Before placing your order, make sure everything looks right; once an order complete, it cannot be edited. We can't add discount codes, modify quantities or shades, or add gifts with purchase—so make sure that everything you want is in your basket. If anything isn't quite right, before placing your order: check our FAQ, read our Easy Troubleshooting Guide, and contact us and we will help as quickly as possible.

HOW TO GET YOUR FREE GIFTS

🖤 These shades are limited edition, and only available while supplies last. After Cyber Monday (December 1), all shades vanish, but they may sell out before then.

🖤 Gifts with purchase stack. You can receive up to all five full-sized shades free—the full limited-edition collection ($149 value)—when reaching the highest qualifying order tier. Qualification is based on your full-sized product subtotal, after applying the 20% sale code.

🖤 Here's how to qualify: Full-sized products in your basket are what counts! Your order must meet the minimum subtotal after the discount to qualify for the corresponding gift(s).

REQUIRED SUBTOTAL (After 20% Code)* Add to Basket Target (Before Discount) Your Free Gift(s)

*Only full-sized products are eligible for the 20% discount and count toward reaching the Gift with Purchase (GWP) minimum. Manual adjustments and order oeview: If a site error results in a GWP appearing in your shopping basket despite the order subtotal failing to meet the required qualifying threshold (after the 20% discount is applied), Rituel de Fille reserves the right to manually remove the unqualified gift during order processing and fulfillment, without prior notification. Customers are solely responsible for ensuring their order meets all qualification tiers.

🖤 We are here to help. We welcome you to contact us by email using our easy contact form, or by emailing contact@ritueldefille.com, and we will get back to you as soon as possible. We are so grateful for you—thank you for being part of this beautiful community.
