This loop brings members of the existing customer community into product development before a design is released. The team recruits and pays women with different body types, bust sizes and heights to test unreleased garments in the fit room. Feedback covers practical fit questions as well as how confident or comfortable the wearer feels. Designers compare responses across participants, change the garment and test again rather than assuming that larger sizes can be produced by adding the same number of inches everywhere. Ho says the fit-room feedback often anticipates what customers later report publicly. The loop therefore turns community proximity into pre-release evidence and gives engaged customers a meaningful role in the product journey.
Origin
Extracted from The Foundr Podcast. Ho contrasts Popflex's current fit-room process with earlier plus-size launches that lost customer trust after proportional sizing assumptions produced inconsistent fit.
Core principles
- 01Bodies do not scale through simple size increments
- 02Testing must happen during development, not after launch
- 03Varied customers expose issues a single fit model misses
- 04Emotional response is part of product feedback
- 05Pre-release feedback can predict public response
How to run it
- 1
Recruit a varied panel
Select community members across relevant body shapes, bust sizes and heights. Pay them as fit models rather than treating participation as free fandom labour.
Pro tip Recruit people who already understand the product and will give candid feedback.
Watch out A panel that varies only by labelled size can still miss important fit differences.
- 2
Test during development
Put unreleased designs on the panel before production decisions are final. Observe fit and movement instead of relying only on measurements.
Pro tip Test the same design across participants in a comparable session.
Watch out Post-launch customer complaints are a costly replacement for development testing.
- 3
Collect functional and emotional feedback
Ask where the garment is tight, loose or awkward and also how the wearer feels in it. Capture recurring responses rather than privileging one opinion.
Pro tip Specific prompts produce more actionable answers than asking whether someone likes it.
Watch out Technical measurements alone can miss confidence and wearability concerns.
- 4
Revise and repeat
Adjust the design based on cross-panel patterns and run another fit cycle. Release only after the design performs across the intended range.
Pro tip Compare fit-room patterns with later public feedback to improve the next test cycle.
Watch out Do not treat a single successful fitting as validation for every size and shape.
In the wild
Ho says early plus-size launches alternated between poor, loose and tight fits because she lacked technical-design knowledge and did not understand proportional body changes. Popflex now hires women from its fan base with varied bodies and heights to test new designs in development and describe both fit and confidence.
→ The team receives pre-release feedback that Ho says resembles the response products later receive in public.
Common mistakes
Scaling every dimension uniformly
Adding a fixed amount across sizes ignores how body proportions change and can create inconsistent fit.
Testing on too narrow a panel
A design that works for one body type may fail for customers with different proportions or heights.
Asking only whether it is tight
Fit feedback should include the wearer's experience and confidence, not only a narrow technical question.
Is it for you?
Best for
It is best for apparel teams developing products across a broad range of sizes, shapes and heights.
Not ideal for
It is not ideal as a substitute for technical design expertise or for teams unwilling to revise after testing.

“we have to test everything in the development process”
“we'll pay them to be fit models”
“the feedback we get there will be the feedback that we get in public”
