What's "sexy" waxes and wanes with time. Fuller girls were in at the turn of the century, then skinny flappers were all the rage in the 20's, being tanned was unattractive until the 1950's, pubic hair is slowly making a comeback, I notice with porn that fake tits are on their way out, and big asses are en vogue.
One of the best things about being a guy is that Men's sizes for a lot of things are measured in inches/cm. When I worked for Banana Republic 20 years ago, the measurement for a lady's size was # inches - 22. So a 30" waist, for example would be an 8. My sister actually wore one of my Grandmother's dresses to Prom (they had a 1940's theme), and my size 6 sister wore a size 14 old school cocktail dress. Marilyn might have been a 14/16 in the 1950's sizes, but she would be a 6/8 today. Twiggy was a size 8 by 1967's standard.

If a lot of fashion designers, like Karl Lagerfeld have their way, they like really tall lanky models, with the excuse that "it makes the clothes look better", then really it's not about the model, it's about the clothes. Hell, if Victoria's Secret only used Twiggy-esque models, they'd go out of business.
Then there's no accounting for personal taste. Personally, Ashley Graham doesn't do anything for me, but that doesn't mean that I think less of her nor the folks who like her. My friends and I have different ethnic / body type / age / fitness likes and dislikes.
Best way to put it - I like black licorice jelly beans. If you don't, that just means more for me.
