RTW Fitting Issues

Over the years of showing people how to create Bespoke patterns I have constantly been made aware that body shapes are like DNA. They may look the same but there will always be differences.

Back in the 1970s I first witnessed this when one of the students in my Bespoke pattern design classes made a wedding dress for her twin sister. They shared a common RTW wardrobe where either sister could wear anything in their wardrobe including shoes. My student made a simple Medieval styled wedding dress. She wanted to see how she would look in it. She was very surprised when she found she could not even get into it.

Then when I started working with quarter-scale fashion dolls at the turn of the century I experienced the difference between Bespoke and RTW. I was intrigued to learn that the companies making these Vinyl dolls relied on very high quality standards to ensure that the body shapes and measurements for a given doll were rigidly maintained through out the mass production manufacturing process. I started to develop patterns for these dolls. I chose the dolls from three different companies.

While some designs would work on all three dolls other designs would only work on the doll from one specific company.

I have had students in my Bespoke pattern design classes ask how they could create patterns for Ready-to-Wear. My only response has been to say that just because a garment fits you, doesn't mean it will fit anyone else.

I wrote Fashion & Costume Design in Quarter Scale to show the different ways body shapes vary. I include the patterns and instructions for making quarter-scale dress forms for 13 models I have personally measured and fit. These Mini-Mes can be used to verify where a given design is likely to fall on a spectrum from Bespoke to RTW.

RTW Industry's Fitting Issues

While the information here is intended for Independent Designers, fitting issues are very relevant for the RTW industry. There is an article written in Italian on SizeBay's website translated as "Why Clothing Sizes Are Inconsistent Across Brands." SizeBay's business is consulting with major garment manufacturers to solve the complexity of selling clothes by eliminating size uncertainty. Here are some of the points this article makes that are relevant to the work of Independent Designers.

  • "Bodies are not standardized. Every human body is unique. Therefore, standard measurements and sizes will never be able to capture the nuances and unique fit and style preferences of each individual shopper."
  • "Clothing itself is not standard: some items are designed to be oversized, others are designed to be more form fitting."
  • "Brands use different fit patterns based on the consumers they are targeting. Consider a brand that caters to bodybuilders versus a brand that caters to petit or plus sized women. Instead of tailoring their clothes to fit some sort of universal standard, brands make sizing choices that are targeted to their specific target audience."
  • "Brands don't want standard sizes. The fit, design, and measurements of a brand's clothing are a form of intellectual properity. Internal size charts are closely guarded secrets."

Lindsey's Fitting Issues

I was surprised when Lindsey asked for help with her RTW patterns. She had already been running a sucessful business for over a dozen years so I asked her what issues she had with the patterns she had been using. This is what she said.

  • "I have very specific needs for my patterns such as the style, fit and sizing (for both my RTW and Bespoke pieces). My previous patterns simply did not offer me the ability to create pieces to fit those needs. In my situation, using a computer program to create patterns caused numerous problems with my finished garments. Instead of following natural contours of the body it made awkward angles causing a poor fit.
  • For my new RTW patterns I needed certain sizes. Being able to base the new set of patterns on already established sizes and scaling them up or down allowed that. This method is much faster than drafting new patterns, especially based on measurements without a dress form or live model."

She had been making her patterns for shirts using a pattern design program which shall remain nameless. I had a similar experience when I was approached by a company making pattern design software that wanted to use my approach to pattern making. When they sent me sample files I found it was impossible to use their software to adjust the patterns for fit or design so I declined to work with them.

The key to making RTW following the approach described here is that the Studio software does not create patterns, it provides the necessary CAD functions to draw and edit straight and curved lines giving complete control over the shape of patterns and a scaling function for changing them to different sizes.
