Is there a word to imply 'used to be beautiful'?

Is there a word to imply when someone used to be beautiful back in the day? I thought of 'ex-beauty' but sounds too harsh. (Though either way it will be inappropriate for the modern age) it's for 60s literature.

Solution 1:

Might I suggest a faded beauty?

Definition: A woman who was beautiful in the past.

I'd also extend it to any commonly thought to be beautiful item, such as curtains, embroidery, furniture or towns.

Solution 2:

Once-beautiful is the expression you want. See https://www.wordnik.com/words/once-beautiful

Solution 3:

For men, the expression former heartthrob seems to be a favourite, but gossip magazines tend to limit themselves by saying someone has aged badly

The expression former beauty queen is well known, and in the past I have heard of actresses being defined former beauties. However, it is (or should be) considered sexist and disrespectful towards women in general and I would avoid telling any woman friend that she was a beauty in her heyday. But on the web, I found a few references:

1. Known as “the first supermodel,” D______ was certainly a beauty in her day.
2. The former heartthrob became a household name with the films Top Secret! and Top Gun.
3. Former beauty T_____ was diagnosed with arthritis, ...
4. Former blonde bombshell and “sex kitten” (very 1960s and '70s)
5. Greta Garbo in her heyday
6. Elizabeth Taylor, the actress considered the world's most beautiful woman in her heyday, ... (source)

Solution 4:

You can use the term erstwhile, depending on how you are referring to it. For example:

Though now old and grey, the audience remembered her erstwhile beauty.

From Wiktionary:

(Adjective) erstwhile:

Former, previous
