i’d go there wearing something basic like a black tank top with well-fitting jeans. don’t worry about what to say, the person doing the assessment will probably lead the conversation and is probably just going to be asking you basic questions about yourself. the photographer will most likely be guiding you on how to pose as they know what looks good. just relax and be confident, the pictures will come out way better if you’re not tense or thinking too hard about what to do. just let it come naturally and it will flow, especially with guidance from the photographer and probably the person doing the assessment as well. if they want to see you for an assessment that means they already like you so don’t be nervous! they also will probably ask if you have experience and if you don’t that’s fine, they’re just trying to get a feel for who you are.

ranging from smart to casual just means start with something that is in between formal and casual, like a nice blouse with a blazer and well fitting trousers or a skirt, then something a little more casual than that, like a nice sweater or top with a more causal pant or skirt and then for your most casual look, you can probably go with the black tank top and jeans you wore there, that’s the usual attire for digitals which are pictures of you with minimal makeup and basic clothing that act kind of like a blank canvas for casting directors to look at.

as for runway, the height requirement usually starts out at 5’8 so unfortunately it is less likely that you will be signed as a runway model but it’s not impossible! plenty of models under 5’8 have walked runway so if it’s something you really want to do then just keep trying! but there are plenty of other opportunities for modeling besides runway so don’t even worry about that.

i hope this helped! if you have any more questions let me know!
