💎 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.
