What to wear to academic conferences

What to wear to an academic conference, pt. 2. I like to bring one work dress and wear it on its own and then layer it with a blazer a couple days later.

Dress- J. Crew, old (similar cut, great winter version for freezing hotels, more affordable)

Wedges- Nordstrom Rack, old (similar)

Purse- thrifted (similar)

Cropped Blazer- old (similar)
