"I don't want a word written on a t shirt to influence the response she elicits from other people. "
Isn't whatever she wears going to elicit a certain kind of response from people? If you dress her in something cutesy, something bland, something stereotypically male etc. Surely there's no way not to, however unintentionally, influence the way people respond to your child by the clothes you choose for them?
This all seems a bit judgemental to me really. You see a child dressed once in a certain kind of thing and are therefore assuming what sort of person the parent is. One day you may see me and DD she might be in a pretty little dress, another day you might think I have a DS because she's gone out in boys clothes. What would you assume about me as a parent based on which day you caught us on?
Almost all the clothes DD has have been given to us by other people, there are very few things we've bought ourselves. If I buy something it tends to have animals on since I love animals - this has included boys t-shirts and booties because I don't think it matters if I put her in green or blue. I don't feel like I'm indoctrinating her into animal worship by dressing her in these things, it just makes me happy because it's something that matters to me.I think some baby clothing is in quite bad taste, but ultimately I don't think the way a parent dresses a child is going to be more important than how they actually treat them, and I don't think you're really in a good position to judge how they'll treat them based on one snapshot from their life based on what they were wearing.
