Best wishes!
Please hold my hand so I don’t text anything to my D, who has invited 44 people to the venue that holds 42 and forgot to count themselves and kids…exhale deeply…going to bed. My dress is the least tonight.
(But if you find something tea length blue and not shiny, please post!)
Don’t worry, dragonmom. Not all invited will RSVP as yes and not all yeses will come 
Deep breath, dragonmom.
A venue for designed for 42 will fit 45 large and 10 or so small humans.
How does this one look like?

I wouldn’t do a thing, I would just ask when and where should I show up and tell them I’d give them a check after I eat.
Congratulations, dragonmom. No ideas - just congrats!
And romani - it’s finally almost here!! Best wishes. The weekend is supposed to be perfect, weatherwise. 
Thanks soozie. I like the first a lot! It’s in the folder for weekend consideration.
Thank you all for the deep breathing recommendation. One cousin will bring small fry to wedding but take them back to the other grandma instead of the reception. Another girlfriend can’t attend. We are close to the Fire Marshall number for the room.

What do you think?
Nice one! And probably very practical, too - it can be worn elsewhere. So it looks like you are considering prints, too? That will open up a lot more options!
That’s very pretty too. I thought you were just looking for solid blue.
If prints interest you and still keeping with blue…there is this dress:
This one is expensive, but it is the type of dress you like from Talbots but the print is in blue:
Or keeping with that same style but for less money:
I want soozievet to shop for me! You have good taste! TBH, dragonmom, I like soozie’s last pick from modcloth or the one from lightbox better than yours. That one seems more like a summer office dress. But it IS very nice! What kind of venue is it? Inside or out? The problem with Seattle in the summer of course, it that it could be 85 degrees or 55…
I LOVE the Modcloth dress. You can formalize it with some simple but pretty jewelry and shoes.
I love this one:

Those models are always so tall. Some of the reviews say it hits at the knee.
This dress is awfully pretty, and could be shortened to tea length if you wanted, and dressed up or down. Fit for almost any weather with a pretty wrap.
I know it’s not blue, but…
Love the Elza J dress! It is gorgeous. Here is another that can be shortened… and is made of silk. The video gives a better idea of what it looks like than the photo does:
