Taom- I think the most challenging thing with tznious today is the inspiration for it!. I grew up MO so tznious was not strict and I have a very close friend who went to Bais Yaakov and she said tznious was so strict but no on really ever explained why.
I think the beauty in what you are doing is that you are looking for your own inspirstion becaise this mitzva is important to you (not to mention comes with so many brachos iYH for your bayis neeman byisroel) but you will iyH be able to inspire your children!
my inspiration was the way I felt about myself. I used to dress in very immodest clothing and when I learned the real halahos of tznious I began changing one thing at a time and seeing how it felt. it was truley a life changing experiance. the day I finnaly decided to wear tights and cover my legs all the time I felt like a new person. I felt like there was me and there was my body and they were two connected beings. it wasnt like I was walking around anymore and worrying if people were starig at me because of my tight skirts. I gained a new respect for myself because I knew everyone who I spoke to and who wanted to be friends with me had nothing to do with the way I was dressed ( and if it did then I knew I was only havig good hashpa on them!)
dressing tzniously has allowed me to really get to know my inner self and find my true happiness because I dont care if boys dint notice me. I frankly dont want them to notice me. my family day in day out make fun of the way I dress and trust me its been the greatest bracha. ive only strengthened my emunah in Hashem through this because I know how happy it has made me as a person in olam hazeh!
sorry if that was so no helpful, but I thoght id give you some chizuk since youve always been such a good friend to me 🙂
