The 27-year-old said she tries hard to keep up-to-date with the latest fashion trends but always feels like shes trying to be someone shes not.

I'm not fashionable, but I love fashion. I think I, uh, try really hard to look good. I think most of the time I fail. But nobody tries harder than me! she told The Cut.

The American actress doesnt blame the clothes she wears for making her feel uncomfortable however. Instead, she blames her awkwardness around fashion and her inability to pull off the latest trends.

Oh, it's so embarrassing. I feel like I overthink things, and I usually end up looking like someone else that I don't mean to be. I feel like people who are effortlessly stylish look like they were born in those clothes, like they were made to wear those clothes. And I always feel like I look like I'm trying to get away with something.

Greta has revealed she admires fellow actress Dame Helen Mirren, 65. She has recently finished filming Arthur alongside the British actress. Greta says she admires her colleagues body and her ability to look so good.
