I will not opine on the specifics. Ask your LOR.
This was alluded to in an earlier comment, and I may be adding nothing except for vocabulary that may make the issue more clear.
Tznius involves two issues. One is halacha. There are varying opinions on several tznius matters that address basic halacha. Is the forearm considered ervah – do elbow length sleeves suffice? This is addressed by poskim. The second issue is the value aspect. Halacha does not proscribe bright red dresses. However, the eye catching colors are provacative. This becomes a violation of the value aspect. Again, I turn to poskim with the erudition and expertise to render rulings on all of this. But our discussion will be enhanced if we are clear about what is clear halacha and what is the spirit of the law.
And, as was noted in an earlier comment, certain shaitels might be more appealing. But is that what Bnos Yisroel should be wearing? I suggest we address the question, and reach the conclusion after careful deliberation. Let us not decide that we want a certain psak, and then engage in the discussion to justify it.
