Atelier is a storefront theme for fashion labels, boutiques, concept stores and curated designer marketplaces. Its voice is an editorial serif with one italic word in every heading, a split lookbook hero, oversized italic category names and a giant wordmark in the footer.
Four styles change the mood, not only the colour: Bone (warm paper), Noir (evening edition), Sorbet (tomato hero panel, rounded images) and Sage (passe-partout frames).
Four styles, one theme
Each style changes the ground, bands, type weight and card treatment, not only the accent colour. Open any of them in the live demo.
Quick size chips on product cards add the right size in one click
Shop-the-look block sells a whole outfit with one "add all" button
Size chip grid with sold-out sizes and a sticky add-to-bag bar on phones
Two products per row on phones, text contrast of at least 4.5:1 in every style
Self-hosted fonts, no extra libraries, works with the 4.21 full page cache
Styled for Kavio Labs add-ons and safe with others
How it works
Install the package in Add-ons: it adds the Atelier theme without touching your storefront. Activate Atelier in Website, Themes and pick a style. Edit the hero texts and links in the Block Manager, choose the products for New this week and Shop the look, upload your logo per style.
A short settings page switches the sticky header, mobile bar, "More" menu, card style, hover image and animations. Updates keep the files you changed; layouts are never replaced.

Demo content matches the live demo: products keep their realistic age (new arrivals and older items) and secondary categories.
Built on the Kavio theme kit 1.1.1 (demo content: optional "show in product list" flag per demo feature and optional time-limited demo deals for themes with deal countdowns).
Fixed 2
Demo content: product features no longer show an internal tag as their tooltip text in the Features tab; upgrading clears the tag from demo features added by version 1.0.1.
Demo content: select and multiple-choice features (for example colour, fabric, size) now get their values, product filters for them are added to the demo categories, and blog posts show their images in the blog list.
Tested on CS-Cart 4.17.2, Multi-Vendor 4.21.2, Multi-Vendor 4.17.2. No breaking changes.
1.0.1

Added 2
Demo content on activation: when a storefront switches to the theme, the theme adds its own demo catalogue (categories, products with images, options and features, blog posts, reviews and a main menu; on Multi-Vendor also a demo shop) on the next admin page and points the homepage blocks of the theme layout at it, so the storefront looks complete at once. Runs once per storefront; re-activating or upgrading never adds duplicates; your own products, categories and pages are never changed. New setting "Install the demo content when the theme is activated" (on by default). Demo items are normal items: delete the ones you do not need in the standard admin pages.
Built on the Kavio theme kit 1.1: department rail, search with departments, header icons and phone blocks, card countdown/spec chip/seller partials, tabbed blocks, in-grid promo tiles and phone helpers (sticky buy bar, filter sheet, swipe gallery, basket bar) are available to the theme.
Fixed 1
The "More" menu no longer leaves a small gap before the first top-menu item.
Tested on CS-Cart 4.17.2, Multi-Vendor 4.21.2, Multi-Vendor 4.17.2. No breaking changes.

Atelier storefront theme for fashion (child of Responsive) for CS-Cart and Multi-Vendor 4.17.2 – 4.21.x, built on the Kavio theme kit 1.0.
Four styles: Bone, Noir, Sorbet and Sage, each with its own logo colours and style icon.
Split lookbook hero with a shop-the-look price pin, "The edit" category tiles with oversized italic names, three promises; italic accent word in section and page titles; footer wordmark.
Lookbook grid and Shop the look block templates (numbered pins and rows, complete-look total, add all to bag).
3:4 product cards with second image on hover, quick size chips (add to bag in that size), hang-tag labels.
Product page lookbook gallery, size chip grid with sold-out sizes, sticky add-to-bag bar on phones.
One-row header (menu, logo, search, bag), mega menu with a "More" item, sticky header, mobile bottom bar, product filters folded behind one button on phones.
Theme settings: sticky header, mobile bar, "More" menu, product card style, second image on hover, product page layout, animations.
Styling for Kavio Labs add-ons (shipping goal bar, labels, videos, alerts, cookie consent, quotes and more).
Domain-bound licence (licence card, badge, notices); without a valid licence the storefront shows the standard Responsive look and the admin panel names the reason and the fix.
Self-healing upgrades: theme files are refreshed after an update, files you changed are kept.
Tested on CS-Cart 4.17.2, Multi-Vendor 4.21.2, Multi-Vendor 4.17.2. First release.
Does Atelier work with my add-ons?
Yes. Atelier is a child of the standard Responsive theme and does not override product, cart or checkout templates, so add-on hooks keep working. Kavio Labs add-ons are styled to match each style.
Does it work with Multi-Vendor?
Yes: vendor pages, featured vendors and vendor blocks are styled. The same package works for CS-Cart and Multi-Vendor.
What happens without a licence?
A new installation works for 14 days. After that, without a valid licence, the storefront shows the standard Responsive look; cart, checkout and orders keep working and visitors see no message. The admin panel tells you why and how to fix it. See Configuration.
Does the theme work on my staging copy?
Yes. Subdomains of your licensed domain and local development hosts are covered by the same licence.
What happens if your licence server is down?
Nothing visible: the theme keeps the last verified result and keeps working for 14 days while it retries.
Does the licence check slow down my storefront?
No. It runs in the admin panel or from cron, once a day; the storefront only reads the stored result.
Will an update overwrite my changes?
No. Files you changed are kept (a notice lists them), and layouts and blocks are never replaced.
A Swiss-editorial storefront theme with oversized type, a ruled category index and four bold styles, built on Responsive so every add-on keeps working.
A department-store theme for large catalogues: colour-coded departments, a department list beside the hero, tabbed product blocks and a sticky buy box.
