Re: Would you..
My inlaws did both valima and shadi dresses.
I get the sense that in Northern Pakistan the girl's side does the shadi dress and the guy's side does the valima dress.
However, the tradition wherever we come from (I tend to be oblivious to all of this, but we're from India, Lucknow, Delhi, etc), is that the groom's side gives the outfits for both days for the bride. And the bride's side gives the groom's outfits for both days. Of course, my parents just paid and let hubby dearest pick what he wanted. My MIL, who is rarely traditional in most ways, wanted to be ultra traditional in this stuff.
So therefore I didn't see my wedding or valima clothes until the day before the mehndi, when my cousins, parents, grandmother, aunts, etc saw the clothes too. (Which is why I glared angrily as my brothers nit-picked over what shade and type of kaam was on their sherwanis for MY wedding, and I didn't have any say in my own clothes other than a general description of what I liked).
I also agree with CremeBrulee, when you show it to a lot of people, everyone is going to have an opinion and make comments that (intentionally or unintentionally) point out flaws in the outfit that may be unimportant, but sort of dampen the excitement.
Keep the showing off to a minimum.
I lucked out tho, because both sets of clothes were very nice, since my MIL has good taste. It's not what I would've picked, but I liked it.
