Privacy & disclosures

What this site is
Costumiser is a costume lookbook: outfits assembled from real product listings, each piece photographed, priced and linked to the store that sells it. There are no accounts and no sign-up.
Affiliate links
As an Amazon Associate this site earns from qualifying purchases. Product links to Amazon may carry an affiliate tag; if you buy through one, Amazon pays this site a small commission at no extra cost to you. Prices and stock shown here are a snapshot and change on the store side; the listing you land on is the one that counts.
What is stored in your browser
Your Keep / Skip switches, the pieces you mark as owned, your main-pick choices and your 18+ confirmation are saved in your browser's local storage so they survive a refresh. So that your list can follow you to another device, a copy is also kept on this site's storage under a random 12-character code, with no name, email or account attached; anyone you give your list link to can open that list. Copies expire after 400 days. Clear your browser's site data to erase the copy on your device.
If you tick the location box on the start screen, the site reads your rough city from your network address to fill in the events search. It is not your precise location, and it is kept only in your browser. Leave the box unticked and nothing is looked up.
Build a look and Advice
When you use Build or Advice, the text you type (and a picture, if you attach one) is sent to this site's server, which passes it to Cloudflare's Workers AI service to draft the answer and returns it to you. The request is not stored by this site. Do not attach pictures you would not want processed by a third-party AI service; pictures of people are not needed, the clothes are what gets read. Requests are rate-limited per IP address to keep the service up.
Advertising
The daytime pages may show ads served by Google AdSense, but only after you choose Allow ads in the consent bar. If you allow them, Google and its partners may set cookies and use device identifiers to show personalised or non-personalised ads; see how Google uses data from sites that use its services and Google ad settings to opt out of personalisation. Choosing Essential only keeps ads off. You can change your choice from the ad settings link in the footer. The after-hours pages never carry ads.
18+
The after-hours deck contains lingerie-based looks and adult products and is for people 18 or older. It sits behind a confirmation gate and is marked with the RTA label so parental-control software can block it.
Pictures
Product photos belong to their respective sellers and brands and are shown to identify the item being linked. Faces are cropped out on purpose. If you own a photo shown here and want it removed, email the address below with the link and it comes down.
