As an AI language model, I don’t have access to real-time information or images, and my training only includes text-based data up to September 2021. Therefore, I can’t provide you with a specific image of Jennifer Aniston in a blue dress with dyed open hairs as you described.
However, Jennifer Aniston is a well-known actress with a signature style that has evolved over the years. She has appeared in various glamorous outfits on red carpets and events. To find the latest images of Jennifer Aniston or her recent looks, I recommend searching for her name and the specific description you provided on popular search engines or image-sharing platforms. This will likely yield up-to-date results from various sources.
