Q: So my fiance is looking for wedding dresses that are way too expensive. When should I confront her and lay down the law? Should I do it now or should I wait until she decides on something that is out of her price range.
A: Ok. You should know by now that laying down the law rarely, if ever, goes over well with women, especially women who are planning for the proverbial "biggest day of her life."
That said, I think that kind of conversation should be had during the beginning of wedding planning. Hopefully, since it's still early in the process, she is rational and have yet turned into bridezilla. After that conversation, I think you should relax and hope for the best. Just because she's looking at really expensive dresses doesn't mean she'll actually buy a really expensive dress.
Also, there is the sensitive subject of who is paying for the dress. I think it's fair that before you're joined in marriage, and in assests, if she decides to spend thousands of dollars on a dress and she's putting it on her card, then there's nothing you can do except to sit and steam over it. But then you see her walking down the aisle, it'll all be worth it.
However, if you're the one paying for the dress, then I think occassional reminders of your agreement is warrented. You may also want to pick your battles. If it's a few hundred dollars over, it may be worth it in time, stress, and perhaps sanity, to avoid that battle and just let her have what she wants. If she decides on an outrageously expensive dress, intervention may be required.
Until the facts are in, I think you should sit back and worry about other things...like how expensive the actual ceremony and reception will be. =) Now the dress doesn't seem that bad, does it? Just saying...
