What it is

Loud is a storefront theme for streetwear and sneaker shops, youth fashion labels, band and creator merch, skate shops and every store that sells in limited drops; on Multi-Vendor it suits creator merch marketplaces.

Four styles change the whole poster: Acid (bone and lime), Riot (black and red), Pool (sky blue and orange) and Newsprint (grey paper, black and one red).

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.

Built for selling

Loud answers what drop shoppers ask first:

  • Is it live: a drop calendar from your real dates
  • Is my size left: sizes on every row, sold-out sizes struck
  • How much: big prices, real sale timers only
  • Add from the list without opening the product
  • A floating bag bar and add bar on phones
  • Text contrast of at least 4.5:1 in every style

How it works

Install the package in Add-ons: it adds the Loud theme without touching your storefront. Activate Loud in Website, Themes and pick a style. The next admin page adds the demo store, so every section is filled at once; replace it step by step.

Drops come from the Available since date and stock, sizes from variations or a Size option, timers from promotion end dates.
