As frum Bais Yaakov girls, we were always taught about middos, and being good to others. To Daven with kavannah, act like a mentsch and dress tzniusdikly.
I hope I checked off all the boxes above.
There is however something they don't mention, which is you can do all the above and still dress trendy look put together. You don't have to be a shluch, and trust me, the moment you hit the Shidduch scene, it's all about looks. As much as I hate to admit it, most people judge but what they see. After all, if you're wearing bullet proof stockings-you must be Chassidish. If you are married and not covering your hair, you must be modern orthodox, and if a guy wears a kapatah, he must be Lubavitch. To a certain extent, our outside reflects who we are on the inside.
Which is why I sorta have to give a bit of credit to author of this post, Ms. Chizhik-Goldschmidt who says it as it is.
For me, personally, I know that as much as looks count, I'm not going to marry a super star or even a model. I know that in the end, personality will win over. I'm BIG on personality, and a guy can look as good as he wants and dress to the T, but if he acts like a diva, or a deadbeat-he's outta my game.
And guys do care about how a girl looks and dresses. Notice on most male dating profiles they write 'looking for someone who is beautiful on the inside as well as on the outside' which is saying it nicely. I've also seen some guys' profiles where they clearly state a preference of hair color/height/skirt size/weight, etc.
So, the point of this post is you can look good, be put together and still be tznius and act like a true Bas Yisrael. Men like to be impressed, and we gotta do our best to impress :)
