Wardrobe impact methodology

Specific actions.
Transparent evidence.

This is the proposed measurement approach for the Closet Passport service. The current Style Circle stores self-reported challenge notes and participation; it does not yet provide a garment inventory or verified impact tracking. We do not convert those actions into broad carbon, water, or “planet-positive” scores unless a future methodology can substantiate the complete claim.

Important scope: The HashtagMyStyle Closet Passport is a personal wardrobe-use record. It is informed by the direction of circular product data, but it is not an EU regulatory Digital Product Passport and does not represent product-level compliance.

Know what’s known. Label the rest.

These are the planned Closet Passport evidence fields. They describe the support for a specific statement—not a sustainability rating for the whole garment. The current site does not automatically verify products or maintain a garment passport.

Verified · source + date

Record the exact claim, supporting document or product-level record, who checked it, and when. A brand’s own claim is attributed to the brand; it is not independent certification.

Estimated · method + assumptions

Show the inputs and calculation. Cost per wear is an estimate when the wear count is incomplete. It does not measure environmental impact.

Unknown · no reliable evidence

Leave missing information unknown. Do not infer materials, labor conditions, certification, or environmental performance from an image, price, or brand name.

Self-reported · action + date

Keep client-reported wears, repairs, borrowing, transfers, and paused purchases separate from independently checked facts. A planned action is not a completed outcome.

A product label or certificate supports only its stated scope. HMS is not a certification body, and an HMS record is not an EU regulatory Digital Product Passport.

Fast tools. Human taste. Your actual closet.

Our service direction is to use technology for organizing information and exploring possibilities, with a stylist responsible for the recommendations they deliver. The current moodboard is a manual planning tool. Automated AI outfit generation and human approval inside HMS+ remain planned features.

A saved outfit, a vote, and a completed wear are different outcomes. StylePoints recognize participation; winning a poll does not make an outfit more sustainable.

Planned Closet Passport records

Garment reactivated

A previously inactive item is worn again and the client confirms the wear.

Repeat wear

A client logs another confirmed use of a garment after the starting date.

Repair or alteration completed

The client confirms that the physical work was completed—not merely recommended.

Item recirculated

The client confirms a completed resale, swap, or donation transfer.

Purchase intent paused

A client identifies a contemplated purchase and confirms that it was postponed or avoided.

Customer savings

The stated price of a confirmed avoided purchase, or completed resale proceeds, recorded separately.

Cost per wear

Client-provided purchase price divided by client-confirmed wears. Unknown values remain unknown.

Outfit combination saved

A complete look the client approves for future use. Saving an outfit is not counted as wearing it.

How recommendations are ordered

We begin with the lowest-input action that can solve the client’s need.

1Rewear what already works
2Restyle it into new combinations
3Repair damage or wear
4Alter the fit or function
5Resell or otherwise recirculate it
6Responsibly replace only when the need remains

How we communicate claims

We use narrow, attributable language. We do not describe a garment, outfit, or recommendation as “green,” “eco-friendly,” “planet-positive,” or “zero impact.” Recommendations explain why they were made, including fit, function, outfit yield, duplication risk, care needs, budget, and cost-per-wear potential.

Source and date attached

Any market or environmental statistic shown publicly is linked to its source and dated so clients can judge its relevance.

Scope stays visible

UK, EU, U.S., and state-level findings are identified as such rather than presented as universal facts.

Estimates are labeled

Projected savings, outfit potential, and future-use recommendations remain estimates until the client confirms an action.

No impact double counting

A repair, resale, donation, or paused purchase is recorded once and is never converted into a broad environmental benefit without a validated method.

Founding pilot safeguards

The Closet Passport is designed to help a client make better wardrobe decisions—not to score, shame, or pressure them. Clients control what they share, may correct their wardrobe record, and confirm outcomes before those outcomes are counted. Partner referrals will disclose any future financial relationship, and shopping recommendations remain optional.

Why we lead with wardrobe value

Recent U.S. consumer research found that price, value, fit, and quality outweigh sustainable production as purchase drivers, while trust in sustainability labels remains low. That is why HashtagMyStyle leads with better outfits, fewer mistakes, and clearer value—and reports specific wardrobe actions instead of relying on vague labels.
