I didn’t mean to imply he wasn’t on top of this. I’m taking a huge step back from it and he is handling his parents completely.
@mom60 - did they have baby sizes (like 9-12 mos? The dress that DS#1 and wife thought baby would wear to the wedding ended up fitting her now and she wore it to the engagement party. DIL is thinking a white dress with a maroon sash (to match the bridesmaids maroon dresses).
@jym626 yes! Looked like they had sizes from infant to girls 14. Some of the fabrics came in all the sizes. Definitely worth a look if you have a Costco nearby.
Thanks. I’ll peek but the dress decision is gonna be my DIL’s. I can tell her to look. I did mention to her that I expected there to be Easter dresses soon that could work as flower girl dresses. The wedding is 4 mos away and I think she was a bit hesitant to figure out what will fit her then.
dIL could buy different sizes and later return.
@jym626 my friend found Target had a nice selection of Easter dresses a few years ago. They found nice flower girl dresses at reasonable prices.
My girls were wearing 9-12 months size clothes when they were 6 months. How old is your granddaughter going to be at the wedding? She may need a bigger size.
@jym626 Dillard’s carries a nice selection of baby/little girl party dresses.
I think the dress I bought her that she wore to this weekend’s event was a 6-9 mo. She is 5 mos now so will probably be in a 12 mo by then. I cant recall if there is a 9-12 mo size??
IIRC correctly…you will see 9 month…then a separate 12 month size. Not a combo. There will,also be an 18 month in some things.
Maybe get two dresses…a 12 month and an 18 month. If the 12 month fits sooner…she can wear it…sooner!
LOL I am not buying the dress!!
@jym626 whoever is buying the dress…should get two different size dresses. Clearly…no way to know what will fit when the time comes!
But it’s fun buying those party dresses…key ingredient…nothing that itches!
She plans to wait until shortly before the wedding to buy the dress. I will mention the Costco sale but there isn’t one near them.
Amazon has a gazillion of white flower girl dresses with all sorts of colored sashes. All priced to wear once and throw out (or use for dress up for older girls). I am sure they are not the quality of those fancy $300 dresses from wedding boutiques, but they look good in photos made by Amazon shoppers. 
Can she order from Costco online?
I guess, but there are vendors that have temporary, seasonal displays in Costcos and I am wondering if this is one of those. @mom60 do you know?
Am also thinking that easter dresses will be on sale after Easter and maybe she can score a deal.
We got our flower girl dress at Macy’s decades ago when we got married (believe it was an Easdter dress, as we married end of May). It was about $30-40, white lace lined in blue and washable.
My eldest niece wore it as our flower girl and handed it down to D who loved it and climbed trees in it, played sports in it, wore it to go to the theater and restaurants and amazingly it still looked great when she finally outgrew it.
We saved it for memories or to make a wedding pillow with or who knows what.
@jym626 I don’t think it’s an outside vendor. I’m sure in a few weeks the same racks will have swimwear or whatever the next holiday is and before we know it Halloween costumes. Most of the chain stores will have the best selection between now and Easter. After that it will be harder to find and she will most likely pay more. But as you said it’s not your purchase. Most of us have learned over the years it’s best to buy something when you see it. The Costco dresses were nice and did not look cheap. At around $16 they are a great buy.
Just looked on Costco online and they do have the dresses. Worth a look.
I looked. I will defer to DIL to find the dress she wants. But thanks!
