Before submitting to every modeling agency on earth and seeing if anything sticks, do your research. Make a list. First, and most importantly, is this agency legit? Can their business be easily verified, and do they have any bad reviews? Is this modeling agency currently accepting models with your look and stats? What is the modeling agency's submission process (specific guidelines vary by agency, but you should be able to find this info on their website)? 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.
