Why Lucy's Formal Wear Fits Better

Discover our unique sizing systems based on 30+ years of expert experience.


Article 1: The Lucy's Difference: Rejecting the "One-Size-Fits-All" Set

In the global children's formal wear market, purchasing online comes with a major challenge. For **Boy's 3-Piece Suits**, this problem is rigid, bundled sizing. Retailers worldwide ship the Jacket, Waistcoat, and Dress Pants as a single-size set. If a boy needs a Size 10 jacket, he is forced to take Size 10 pants, even if his waist is a perfect Size 9.

For **Flower Girl Dresses**, the challenge is different but just as frustrating. A standard dress might fit your child's chest perfectly but be the wrong length, or it might be the correct length but far too wide for their body type. Children simply don't come in "standard" shapes.

At Lucy's, we leverage over 30 years of hands-on, in-store fitting experience from our New Zealand retail store. We've seen every body type, and we've built our online store to reflect that real-world expertise. We have rejected the inflexible "one-size-fits-all" approach.

Article 2: Our Solution: The "Mixed & Match" System & Expert Advice

Our systems are designed to give you the flexibility and confidence you deserve.

For Boy's Suits: The "Mixed & Match" System

Our unique system gives you complete flexibility. You pay for one suit but can select two, or even three, different sizes for each piece to build the perfect fit.

A Real-World Example: A boy is 130cm tall with a 62cm waist. At a traditional retailer, he's a problem. At Lucy's, he's our specialty. We would recommend:

  • Dress Pants: (Size 9) - based on his 62cm waist.
  • Waistcoat: (Size 10) - based on height and waist.
  • Jacket: (Size 9) - based on his height.

The customer receives a suit blended from Size 9 and 10, perfectly tailored to his unique shape. In fact, you can select any combination you need—Dress Pants (Size 14), Waistcoat (Size 15), and Jacket (Size 12)—all for the price of a single suit.

For Girl Dresses: Expert Sizing Advice

For Girl Dresses, our solution is our expertise. While a dress is a single garment, our 30+ years of fitting experience allow us to provide unparalleled advice. By reviewing your child's full height, chest, and waist measurements, we can recommend the absolute best size to achieve the desired look. We can even assess (optional) photos you provide to judge body type, ensuring the final fit is flawless.

The Complete One-Stop Outfit

Customisation doesn't stop with the suit or dress. On the same product page, you can select "Additional Items" to complete the entire look:

  • Trouser Alterations: Get the trouser length hemmed perfectly.
  • Shirts: Choose from different colours and sizes.
  • Ties & Bow Ties: Select your preferred style and colour, not a fixed set.
  • Shoes: Add the perfect pair of shoes in the correct size.
