Era — how much of a decade carries
Does a decade tag actually produce that decade?
A decade tag sounds like it should change clothing, hair and interior finish at once. It did not carry that far.
The four cuts differ a little in palette and silhouette, but naming the decade from the picture is hard. What did come through is written below.
Every cut below shares one seed, one base prompt and one sampler setting, and differs only by the tag marked in amber.
What each cut shows
1920s- Dark top over a burgundy skirt — the palette moved before the period did.
1950s- A black dress, with a silhouette almost identical to the previous cut.
1980s- The clearest of the four: a bright top and a high waist.
2010s- Indistinguishable from the default — this is effectively where the model already lives.

Takeaway
Do not ask a decade to do the work alone. Name the things that belong to it — garments, props, interior finishes.
How far this result reaches
The parenthesised style form, 1980s (style), is a different tag and works far better — see the medium comparison.
Measured on a single Stable Diffusion family checkpoint. The same tags can behave differently on NovelAI, Midjourney or another checkpoint. This is a reference point, not a verdict.
