💎 Why Designer Dresses Are Worth Investing In
Before we start shopping, let’s define what makes a designer dress a true investment:
Qualities | Description |
|---|---|
Timeless design | Think minimal silhouettes, premium fabrics, refined finishes |
Quality construction | Lined, reinforced seams, expert tailoring |
Resale potential | Coveted brands retain or increase in value |
| Cost per wear | A timeless £800 dress worn 100 times = £8 per wear—a bargain |
Tellar’s sizing tool ensures your designer purchase starts off right—sized precisely, styled beautifully, and worn often.
