Liza is in conversation with Alicia Esposito of Future Commerce to discuss the impact of GLP-1s on fashion. It’s not just that shoppers are buying smaller sizes…which still don’t fit. The problem is how garment sizes are created in the first place.
Here is what was discussed:
Bodies are significantly changing, and very quickly. Within weeks, in some cases. And brands can’t keep up because they’re not set up to keep up.
One reason is that every brand develops its own sizing standards. There’s no universal standard anywhere in the world.
Each brand creates what’s called a master fit block, which is a set of measurements that represents each of its sizes, from small to medium, large, and so on.
From that block, the brand creates and grades patterns, which means scaling those measurements up and down across the full size range.
That master fit block, the foundation, is updated every 3 to 5 years.
A consumer’s GLP-1 body shape and size could change multiple times throughout a single season.
