Who are the agency's past and present models? What are the modeling agency's most recent campaigns? Are they working with established brands and companies? Do you WANT to have this agency represent you, meaning you will be representing them in turn? Once you find the modeling agencies that you feel confident to be a good fit for you, submit digitals to your top picks. After you submit your digitals if you receive a call to meet with an agency in- person, do even more research prior to the meeting. Brush up on prominent fashion designers, who the 'it' supermodels are at the moment, current events from the fashion/beauty/modeling world, etc. You don't need to be a walking "fashion model encyclopedia" by any means- be aware and informed.
