Theory
With Theory our usual method stops at the door. We still write what is documented, and say what is missing.

How much this brand discloses, and how much of it we could verify. It is not a quality rating — a composition line cannot tell you how good a fabric is. How we calculate it
- Production disclosure 0/25
- Linked sources 16/20
- Own material check 0/15
- Fabric weight stated 0/12
- Country stated per product 0/10
- Construction detail stated 0/10
- Cost breakdown published 0/8

The page stays closed
On 30 July 2026 we tried to open a Theory product page — via theory.com and the European shop, with our retrieval tool and with a regular browser. Every attempt ended in a block page and status code 403.
We could therefore record neither price nor composition nor any statement of origin. This is not an accusation — a shop may restrict access. It only means that nothing stands here, rather than something second-hand.
What can be documented
Theory was founded in New York in 1997. Fast Retailing took control in 2004 and has run the brand as a wholly owned subsidiary since spring 2009 — the same group as Uniqlo and GU.
The group publishes a list of its production partners with factory names, addresses and workforce figures. Whether and which of those factories work for Theory does not follow from the list: it has no brand column, and the corporate page names no individual brand in its scope.
What that means for classification
We do not classify Theory as forthcoming.
The group’s factory list is considerable, but it is a group disclosure. For Theory itself we hold not one checked statement — and a group list without brand attribution does not substitute for one.
Nor do we classify the brand as opaque.
We simply do not know what its product pages say. As soon as we can read them, we will add it.
Verifiable statements with a source, not a rating. We publish no ethics score of our own — for that, follow the external link.

Questions readers ask
Where is Theory made?
We could not establish this. Every request to a product page ended on 30 July 2026 with status code 403, including in a regular browser.
Who owns Theory?
Fast Retailing. The group took control in 2004 and has run the brand as a wholly owned subsidiary since spring 2009; Uniqlo and GU belong to the same group.
Does the group factory list cover Theory?
That cannot be read from the list — it has no brand column. The corporate page names no individual brand in its scope.
Why is there so little here?
Because we write only what we can document. The product pages were not retrievable for us, and we do not repeat second-hand claims.
