System Requirements Document (SRD)

Project Name: happy-clothes

1. Introduction

Welcome to the happy-clothes System Requirements Document (SRD). This document outlines the functional and non-functional requirements for the development of happy-clothes, a modern, Gen Z-friendly platform where users can buy and sell old or new clothes at affordable prices. Additionally, the platform will feature a unique "create outfit" tool that allows users to upload photos of their clothing items and receive outfit suggestions based on current trends.

This project is designed to cater to a tech-savvy, eco-conscious audience, particularly Gen Z, by combining sustainability with creativity and individuality. The platform will feature a modern, minimal, and visually appealing user interface, infused with Gen Z slangs and trends to ensure relatability and engagement.

2. Outfit Creation Tool: Allowing users to upload photos of their clothing items and receive outfit suggestions based on trends or other uploaded items.
3. Trend Integration: Leveraging AI to analyze fashion trends and provide personalized outfit recommendations.

The platform will focus on simplicity, creativity, and eco-consciousness, making it a go-to destination for Gen Z users in India. The system will support INR as the default currency and operate in IST (Indian Standard Time).

6. Signature Design Concept

Interactive Digital Wardrobe

The homepage will feature an Interactive Digital Wardrobe that acts as both a visual centerpiece and a functional tool.

• Visuals: A 3D wardrobe animation that opens when the user hovers over it. Inside, clothing items (shirts, pants, accessories) will "float" and rotate gently, inviting users to explore.
• Interactions:
  • Users can drag and drop items into a "virtual mannequin" to create outfits.
  • Clicking on an item will display its details and allow users to purchase or upload similar items.
• Animations: Smooth transitions with subtle bounce effects when interacting with wardrobe elements.
• Color Shifts: The wardrobe background will subtly change colors based on the time of day (e.g., soft pink in the morning, deep blue at night).
• Micro-interactions: When users rate an outfit, a confetti animation will play, adding a playful touch.

This concept ensures that the homepage is not only visually stunning but also highly interactive, leaving a lasting impression on users.

7. Non-Functional Requirements

• The platform must load within 3 seconds on both desktop and mobile devices.
• The system should support high-resolution images for clothing uploads without compromising performance.
