I would have a real problem paying $1,500 for a polyester dress, especially one like the Jason Wu that OUGHT to be silk.
I think that the second dress is too much like a bathrobe at first glance.
The third dress is rather charming. Whether it looked smart or a bit juvenile would depend on your height, figure, and hairstyle, and what kind of hat you might choose, if you plan t wear one.
I think you should keep looking. 
So, getting back to wedding moms and dads, we are a week away, and I am still waiting for DS/fiancée to email the welcome letter so I can print it. They are out of town at another friend’s wedding. I don’t do well with last minute stuff. I am a planner. Wish they would get it done!
I bought the Jason Wu - my D also thought it was the best choice. I used to consider polyester inherently bad, but there are now some really beautiful synthetics that are actually much nicer than cheap silk. I agree that the middle one could look like a bathrobe, but I’m tall and slim, so I can wear longer dresses and things that overwhelm most people. That said, it’s so flow-y that it will definitely hide my figure. I have some sparkly silver Aquazurra sandals that I’ll wear with it and maybe a metallic clutch. I don’t do the bright color with black thing, ever.
I really hoped to find a pretty floral, but most are very dowdy. I went to the Newport Flower Show yesterday and it was a sea of floral dresss - and some, oh my, were pretty bad…shockingly bad, actually. Quite a few ancient women dressed to the nines in head to toe flowers, including elaborate hats.
@BunsenBurner I bought a load of Akris Punto tropical leaves - I’m going to wear the long skirt to the show tomorrow. Akris or Akris Punto really didn’t have a nice summer wedding appropriate dress this year 
That dress is great, @Consolation - I’m not familiar with that designer, but I’ll check her out.
The second dress reminds me a little bit of this dress that Megan Markle wore at a wedding https://www.eonline.com/news/944789/meghan-markle-nearly-tumbles-in-floral-dress-at-prince-harry-s-cousin-s-wedding
I hope @jym626 that you get your welcome letter soon.
I just emailed the party planner and coordinators for the rehearsal dinner and welcome party, and the people bringing the desserts for the rehearsal dinner. Hope its not overkill, but we are planning from far away and have other things to juggle when we arrive. They are all a little too laid back for my comfort zone!
Go for it, @jym626. Planning from afar has its challenges. I learned that some consider plans all locked down a bit pre-maturely. Your peace of mind counts.
Thanks, @travelmut. I realize I over-plan, but I would prefer to avoid a problem than deal with it when it happens.
I am all about planning and confirming. Many times. Plus having backup plans if needed.
D’s wedding is August 2019. She thought her MOH friend would be ideal to confirm everything the week before. Trying not to act horrified, I just said you know I am way too anal to delegate anything before the wedding day. I am happy to let the on site day of coordinators handle the day, but I’ll be watching. She just laughed.
oops @travelnut !! Apologies for the typo (thought it did make me smile when I read my typo) ;
Jym - hugs. I am a planner, too, and I know how you feel!
D has a week off, so she and FSIL are flying in today and staying until Wednesday. We moved here without her in January, so this will be the first they will see our new place. We will take a field trip on Monday and she her venue for their wedding in December. It is about 4 hours from me, half way across the country for them. It will be nice to see it in person!
Speaking of a post that said a long flowy dress made Meghan lose footing… it was not the dress:

I am all for beautiful shoes, but not torture shoes! 
Re: planning and confirmation…
We parents of the bride were hosting the wedding so WE confirmed everything related to that…and believe me…much of it was due to the venue long before the prior week. The final guest/dinner count, table arrangements, time for flowers to be delivered, payments to florist venue, band, hair makeup folks, place cards for guests, time that photographer and second shooter were arriving, meet and greet arrangements, day after brunch…etc.
NONE of that was anything the MOH could do…none of it.
The MOH communicated info to the bridesmaids…and really was very helpful with that. She also planned and did all the arrangements for the little bachelorette which was held two days prior to the wedding.
But MOH confirming wedding things…nope.
We are paying directly (and coordinating) the Friday night events (and doing the hospitality bags and welcome letter). And paying for the party planner. Party planner coordinated the hair and makeup person, and we will each pay for our own. Bride/groom and party planner (I hope) coordinated everything else. We are paying the wedding expenses, but via (through) the bride and groom. So its weird being the wallet but at arms length for much of the planning.
@jym626 -similar situation but I have even less decision making power. I’m going to suggest a welcome letter.
I made hair and makeup appointments this week for myself and my two daughters. We will go to a salon near the venue that was recommended by the planner. I’m glad to have that out of the way. Wedding is Late September and I hope they get the invitations out soon.
My H and S are out suit shopping for my S. He has strong opinions about what he wants to wear. We don’t have many options so they headed to another city that has more shopping options. It’s a bit scary sending two males off shopping alone.
With wedding number 2 which is next June my D is moving along securing vendors. She has a great wedding planner which is making things much easier. Next weekend my other D and I will go up and go dress shopping with my D. Her future sister in laws and Mom will join us. I’m hoping to also be able to look for shoes for the September wedding when we are up in the Bay Area.
Both my girls still haven’t figured out what they are wearing to the September wedding. One of them has ordered and returned over 20 dresses to Nordstrom.
@mom60- plan is for me to go with MOB to costco or target (which aren’t far from the hotel) and send recommendations to the bide for approval of what to put in the bag. Sigh…
D1 was a real planner. She sent out emails to let guests know when and where they needed to be for various events. She sent out emails to families on where they were to sit during the ceremony. The bridal party had a detailed time schedule for makeup, pictures, pick up to the ceremony, etc.
We had tips envelopes all ready for the wedding planner so she could give them out on the day of.
D1 wanted pictures taken around her college campus, so we had a shuttle to move the photographers and videographers equipments.
I know D1 probably scheduled more than other people…The bride and groom gave gifts to their bridal party, gifts to parents, first look, private moments with parents (I helped D1 putting her dress on, groom’s father helped with his tie) we had tea ceremony, etc. The day of was a long day between makeup/hair (2 hrs/person) and pictures, so we brought in food/drinks for people in the wedding. It is important to schedule all of those things you want to do and let the wedding planner and photographer know, otherwise you may run out of time and not have pictures taken.
We did a walk through with the photographers and videographers few days before the wedding, so they knew when and where all the important moments were going to take place. Our wedding planner orchestrated with the DJ/photographers/videographers on when the first dance, mother/father dances, speeches were going to happen. If we didn’t do that then a lot of moments may not be captured.
@jym626 last summer I went to a wedding and they had Kind bars in the hospitality bag. They were from Costco and were a big hit with everyone. Another wedding I went to the bags contained snacks that the bride and groom loved. I’m sure my S and fiancé haven’t even thought about bags.
