I often have trouble picking characters for cosplay ideas, but your mention of a lab coat did give me an idea to go as Kurisu from Steins;Gate at some point, which for me would be very doable!

And yeah on the height thing I’m like 5’10 and while I don’t feel crazy tall, when I get the courage to survey my surroundings and look at other people it’s like 90% men at my eye level which feels weird sometimes
