Getting as much internship experience as you can is infamously necessary for future success in any area of the fashion industry (via G&M Fashion Career). This experience will help you learn how to succeed in the industry, give you a taste of a day in the life of the job, and show future employers that you're passionate about fashion. If you want to find a fashion styling internship, you can start your search by simply looking up "fashion styling internships" on Google, Indeed, and LinkedIn. You should always consider location when searching for an internship; even if the position sounds like a dream come true, you have to make sure you'll have a realistic transportation plan, especially if the internship is unpaid.
While traditional job-searching methods and websites like Indeed and LinkedIn can be great, you'll benefit from using more specific resources — such as Intern Queen, FreeFashionInternships, and StyleCareers. Even if you can't find an internship in styling, internships in similar aspects of fashion, such as visual merchandising, will still be helpful. If there's a brand or company that you're obsessed with and would love to intern for, it can't hurt to reach out. Of course, do your research regarding who to contact, carefully plan what you want to write, and don't expect a reply, but shooting your shot could potentially lead to something life-changing.
