+# Outfit Style Guide
+
+This guide outlines the preferred styling logic, brand affinities, patterns, and structure for Crystal's outfits, emphasizing **bold pattern mixing** balanced by **pure accessories**.
+
+## I. Core Preferences and Prohibitions
+
+| Category | Preference (✔️) | Prohibition (❌) |
+| :--- | :--- | :--- |
+| **Brands/Material** | **Sacai** brand; **Denim** items | - |
+| **Patterns** | **Plaid, Stripes, Floral, Leopard Print**; Active pattern clashing (min 2) | Monochromatic or single-pattern outfits |
+| **Layering** | Max **2 items** on the upper body; Pattern mixing replaces layering | Excessive layering (叠穿) |
+| **Fit/Silhouette** | Accepts **Oversize**; Flexible (can mix with slim-fit/leggings) | Tight-fitting or complicated silhouettes |
+| **Shoe Styles** | **Boots, Platform Shoes, Pointed Low Heels, Mesh Shoes, Ballet Flats, White Sneakers** | Full High Heels (高跟鞋), Tall Boots |
+| **Bags/Shoes (Pattern)** | **Solid Color** only for bags and shoes | **Patterned/Printed** Bags or Shoes |
+| **Bags (Material)** | Must be **Leather** (or natural elements like Rattan/Wicker) | Non-leather materials (except rattan/wicker) |
+| **Accessories** | **Gold Tones**; **Necklace** (Mandatory); Rings, **Hoop Earrings**, Bracelet, **Watch** | Vector-style accessories |
+
+---
+
+## II. Styling Pattern: Pattern Clash and Pure Balance
+
+This stylist's style prioritizes visual impact through **clashing prints** rather than layering. Outfits are usually based on a bold print or denim, balanced by pure, solid-colored accessories.
+
+### 1. Classic Outfit Examples
+
+| Style | Structure | Keywords |
+| :--- | :--- | :--- |
+| **Edgy Casual** | Milk Tea Oversize Blazer + Beige Shirt + Olive Green Cargo Pants + Black Pointed Low Heels | Utility, Sharp Contrast, Subtle Prints |
+| **Elegant Flow** | Milk Tea Oversize Blazer + Beige Shirt + Dark Brown Slim-fit Pants + White Mesh Shoes or Ballet Flats | Mixed Fit, Comfort Contrast |
+| **Sporty Mix** | Milk Tea Oversize Blazer + Dark Brown or Leopard Print Yoga Set + White Sneakers | Athleisure, Pattern Pop |
+| **Heavy Print** | Floral Dress + Denim Pants + Rattan Bag + Wrist Cord + Layered Beaded Necklaces | Pattern Clash (Floral + Denim), Natural Accent |
+
+### 2. Outfit Extended Rules Summary
+
+1.  **Pattern Clash**: Actively mix **at least two** patterns (Plaid/Stripe/Floral/Leopard) in one outfit to maximize visual interest.
+2.  **Layering Limit**: Do not rely on multi-layering for depth; use print complexity instead. The upper body is limited to **max 2 pieces**.
+3.  **Fit Flexibility**: Oversize is welcome, but tight-fitting items (e.g., leggings) can be mixed. Prioritize durable fabrics like **Denim** for texture.
+4.  **Color Base**: No strict color restrictions on garments, but all major accessories (**bags and shoes**) must be **pure, solid colors**.
+5.  **Shoe/Bag Principle**: Shoes should provide height (low heel, platform, boots). Bags should be **leather and solid-colored**, with rattan/wicker bags accepted as natural accents.
+6.  **Accessory Requirements**: **gold** jewelry is preferred for unified tone. **Necklace** is mandatory (min 1). Earrings must be **hoops**. Stack **bracelet/ring/watch**.
+7.  **Overall Balance**: If clothing patterns are complex, shoes/bags must be **simple and pure** to ground the look. Style leans toward **mixed-casual and energetic**, avoiding blandness.
+8.  **Scene Adaptability**: Add **cargo pants/low heels** for casual settings; **yoga sets** for sportier looks; use **denim** to balance out heavy prints.

+## II. Styling Pattern: Layering and Balance
+
+This stylist's outfits emphasize **comfort** and **layering** (creating depth). The common structure is: **3 Upper Body Items + 1 Lower Body Item**. The pattern mainly uses solid primary colors, mixed with subtle patterns, aiming for a look that is **relaxed and casual yet polished**.
+
+### 1. Classic Outfit Examples
+

+
+### 2. Outfit Extended Rules Summary
+
+1.  **Color Palette**: Main garment colors are limited to **Black, White, Gray, and Earth Tones** to ensure a minimalist foundation. Accent colors in accessories should not exceed 2.
+2.  **Layering Principle**: A minimum of **2-3 layers** on the upper body, with patterned edges (e.g., shirt collar, scarf) visible to add depth without complexity.
+3.  **Fit Requirements**: All items should lean toward a **loose/oversize** fit to prioritize comfort; tailoring must be **clean and sharp**.
+4.  **Pattern Restriction**: Only **plaid/checkered or stripes** are acceptable as subtle accents; **strictly no florals**, unless an extremely minimal exception is made.
+5.  **Shoe/Bag Coordination**: Footwear must be **flat and casual** (white sneakers are preferred); leather bags must be **pure black or white**.
+6.  **Accessory Stacking**: At least **2 gold necklaces** must be layered; a **watch is mandatory**; earrings/rings should be minimal, avoiding large volumes.
+7.  **Overall Balance**: When the upper body is complex (layered), the lower body should remain **simple**; the overall style is **neutral and polished**, avoiding highly feminine heels or boots.
+8.  **Scene Adaptability**: Add a **tie** for formal settings, **shorts/socks** for casual settings, or **leggings/fanny pack** for sporty looks, but always maintain core comfort.
