“How You Do Marketing”: Sydney Sweeney Stuns Fans By Flashing The Camera In Latest Lingerie Promo

However, not all feedback was glowing. Some viewers questioned whether Syrn’s sizing truly lived up to its inclusive messaging.

“As someone who also has very large naturals I really wanted to love this line,” a commenter wrote.

According to a 2020 study by Curtin University, women with larger breasts are more likely to experience upper back pain than those with smaller busts. For every one-size increase in breast size score, women were about 13 % more likely to report upper back pain.

At the same time, poor underwear fit is a common factor in discomfort for larger-breasted women, with proper support being linked to a reduction in back and shoulder pain.
