This varies GREATLY from school to school. If you're at a school where recruitment is very laid back, insisting on manicures and things of that nature is going to make you come off like the bitchy/prissy sorority. Also, don't require things that can be outright unhealthy (like tanning or straightening hair). Just say if you do tan, it should be even...if you do straighten, it should be done right not half-assed.

You should tell the girls what they have to buy BEFORE they go home for the summer (because not everyone lives in a town with a decent mall and they might only make one trip to it while school's out). Rather than just saying "get a black shirt" - find a few that will suit your purpose and have the girls purchase one of those - SPECIFY STORE AND STYLE BY NUMBER. Your school may have regulations about everyone wearing the exact same piece, which is why I say pick a few (enough to get you over the hurdle). Everyone has different definitions of words like classy, tailored, businesslike, etc etc etc. and just saying "you have to wear XYZ77124 from Old Navy" results in a lot fewer hurt feelings than making a girl go out and buy something, having her get it back to school, and then telling her she's wrong (even if you do it nicely)

Oh and if you have bigger or shorter or taller or boobier girls in your chapter, don't pick styles that will make them look horrible.

ETA: refreshing myself on your other posts, you definitely need to tread lightly on the bolded. It sounds like you're going from quite laid back to quite not and if not done properly, it can really backfire. Some of the girls no doubt joined BECAUSE your group didn't have as many rules and regulations on things like this.
