It seems like you are saying that to be a supermodel you have to have been at your peak during the supermodel era, I have a different point of view. As I said previously, the reason why that period of time is referred to as an era is because there were several supermodels being supermodels concurrently and not just one or two, but there can be a supermodel being born right this second.
I do wonder what your personal definition of a supermodel is, given that you wouldn't consider Stephanie and Helena supermodels.
I'd like to point out that during the early 90s, Stephanie was in a relationship with Axl Rose (from the band Guns N' Roses) and she appeared in a couple of the band's videos (she even wore a Versace bridal gown in one of the videos). And Helena appeared in the famous "Wicked Game" video (which aired on tv during the same period in 1990 as George Michael's "Freedom" video). For the members of the public who weren't already familiar with Helena, that video served as their introduction to her. What better way for a model to gain additional exposure in the public eye than by appearing in popular videos put out by popular musicians?
Kate Moss during her hey day was as recognizable in the US and elsewhere as the 90s supers were during theirs and probably more, save Cindy Crawford. She was the Calvin Klein girl (and Calvin Klein jeans and underwear are commercial products) and she dated Johnny Depp, that parallels Claudia being the Guess girl and dating magician guy.
When I think of Kate Moss' heyday, I think of the waif model period of the mid-90s, and I'm pretty sure that when people who followed fashion in the 90s hear the name Kate Moss, the word "waif" comes to mind. The waif model trend didn't really serve much purpose, and some of the models from that period (including Kate) became associated with the whole "heroin chic" thing. Also, there was a particular year (either 1995 or 1996, I can't remember exactly) when Amber and Shalom were considered the top models of the moment. They even jointly hosted MTV's House of Style show, succeeding Cindy Crawford.
And Kate was never "the" Calvin Klein girl. Firstly, she wasn't the only female model to appear in Calvin Klein ads during the circa 1993 period. There was another female model in the ads (who even appeared in a couple of the ads alongside Kate), but her name escapes me at the moment. And secondly and most importantly, Christy Turlington was
thee Calvin Klein girl, as she had a $12 million contract with the label, which began in the late 80s and spanned several years. Regardless, those Kate ads never had the type of public impact that Claudia Schiffer's Guess ads had. Can you say, Brigitte Bardot lookalike?
Also, ever heard of the Fashion Cafe??? It was a venture of restaurant chains jointly owned by Christy, Claudia, Naomi, and Elle, akin to the likes of Hard Rock Cafe and Planet Hollywood. The Fashion Cafe chain was established sometime in 1994 or 1995. So to assume that Kate Moss surpassed that type of public recognition is just absurd.
Everything you are saying about Linda applies to Kate Moss, Kate can go and live on Mars for five years and when she returns she will be on the cover of Vogue Paris, and would probably have been on the cover of ten British Vogues during her absence. Conversely what you are saying about Kate applies to the supers, once their hey day ended so did their recognizability outside of their home countries unless they were caught up in a scandal like Naomi. Although they probably also maintain recognizability among the people who were really into them, so there is probably a niche of people who will always recognize Claudia as the Guess Girl and Kate as the Calvin Klein Girl.
For all I care, Kate Moss could land on the cover of British(!) Vogue
every month of next year starting with January, yet the only people who would actually care to know about it would be a)people in the UK and b)her fans. A no-name model like Natasha Poly could also disappear for five years, and then come back, and guess what? She too would be on the cover of Vogue Paris upon her comeback. That doesn't prove nor indicate anything.
And if you wanna claim that the supers' recognizability ended outside of their home countries after their heyday, then how do you explain the fact that Linda Evangelista was the model who was chosen to appear on the cover of American Vogue in 2006, after the magazine had featured only non-models on its cover for over a year? Linda isn't American, she's Canadian. Why would Vogue take a chance like that, unless she's
somebody who's recognizable to the celebrity-worshipping American public?
