Mytake: even when working on the same issue (tznius), we all have different things that “speak” to us. First of all, i found “inside, outside” excellent; though what helped more was hearing her in person give a speech. (also, the 6 diaries was interesting, though i read it after tznius became a non-issue for me.)
i still had issues with how i dressed – different than yours. but what really helped it become a non-issue was something that i think may apply to you also. from reading your posts, it seems to me that you’re a person who truly is trying to grow. What may be happening is that the way you are dressing externally does not reflect anymore who you are internally. this may have an effect on the type of shidduchim that you are being redt – for you may actually be misrepresenting yourself.
popa may not be so far off. best advice may be to go on a shopping spree and look for outfits that you look great in, but are also perfectly tznius. you should look nice, but they should reflect how and who you are internally. and then, throw away all your old clothes. even if you do not have the money for it, charge it on your credit card. i did – and the next person who i went out with later confided to the shadchan that he really liked my style of dressing. that guy ended up paying for all those new clothes after we got engaged. 😉
