Ok in all rights, Gisele didn't quit. She demanded a pay raise, and they didn't give it to her. So in all rights she was kind of fired. Which IMO was funny, because they turned around and pay Adriana more, than what Gisele wanted...(in fact they even pay Ale higher than what Gi demanded)
Most models would rather do commercial, and I'm sorry any model who drops a 25-30 million dollar contract, along with a good 5-10 million beauty contract on top of it...to do High Fashion is insane. Adriana was the ONLY model a couple years ago to have 3 multi year multi million dollar contracts...surpassing Gisele.
I'm not saying your opinion is wrong, I think we're just saying to say she's just commercial is absurd, or saying she isn't doing it now because she can't, is absurd. Adriana's shown she can, she just basically doesn't want to, she's happy doing what she's doing..but when she does get back into it, jobs are thrown at her...like they were for a couple months before she got pregnant.
Honestly, most people that I've seen, I've heard of know Gisele for 3 things...being with Leo Dicaprio, being with Tom Brady, or being with Victoria's Secret, heck the night of the VSFS I had to reply to I bet 200-300 people wanting to know where Dri was, but I bet half of those people wanted to know where Gisele was...she's been gone for 3 years! Honestly if HF was as important as some people make it out to be, she'd be getting more and more famous for that...obviously it hasn't. Maybe inside the fashion world, but to the general public...she hasn't. So Gisele hasn't made fame out of her high fashion career, as so many people want to think to the public. Because if that was the case she wouldn't be famous for VS, and who she's dated and most of the public wouldn't be still wondering why she's still not with VS...if she was as famous with HF as some people like to think...they'd know where she was and why she "quit" VS. heck I was shopping in VS on black Friday and heard some woman ask where Gisele was, she didn't see anything with her on it...and the woman replied "I don't know" just then the clerk that was helping them said "Oh, she doesn't model anymore" and then they started talking about her "dating that football player" So while inside the fashion world, she might be a big success, her fame comes from VS...not HF, at all.
As for people who say tons of people who live in Brazil look like Adriana...I've always thought this when I hear something that ridiculous...if tons of girls do, and tons upon tons of girls come to the US to model from Brazil...why do the hundreds we see never look like her...question to ponder. But anyway

But again we all have different opinions. But that's just what I've observed.
