Getting ready outfits—worth it or no?

Probably a know-your-crowd thing. Do you think your girls will care if you ask them to wear something specific? Most probably wouldn't care. The button ups are good for not messing up hair but zip ups could do the same thing. You could get them something like this since it will be warm.

If they don't already own them, I wouldn't expect them to go out and purchase something for your getting ready photos.

The button and zip ups are great so they don't mess up HAMU. If you are letting them pick a top of their choosing that they already have, a pair of black leggings goes well with pretty much everything.

ETA: I didn't do getting ready photos. They were not something I needed day of, so if you don't want them you can just have your party in whatever they feel comfortable.

I didn't have a "getting ready" outfit. Until it was time to put my dress on, I wore a baggy t-shirt with a stretch collar (to fit over my head after my hair was done) and yoga pants. The photographer took a few pictures of me in that outfit standing with the dress. I forgot my robe at home. I didn't do the matching robes with the bridesmaids. I told them to just how up at my hotel room in their dresses. My sisters were staying in the same hotel, so they waited a little longer, but my two friends showed up in their dresses.

I personally feel like it's not worth it

I'm just telling my girls to wear shorts/leggings and a neutral colored top (recommending button up or zip up for Hair & Makeup purposes) of their choice. I want them to be comfortable. I also have girls in a very wide range of clothing sizes, so trying to find something that everyone would be comfortable in would be a headache for me that I just don't need. Instead I'm using that money to buy them a nicer personal gift.

Not worth it, in my opinion.

I added patches to plain black sweatshirts for my Princess Posse! On the day of, we wore black leggings as well. Hopefully, the outfits made it into the video because we totally forgot to take pictures the day of. Here is one of me while getting ready and some of us chillaxing after the big day

Hmm, it seems to me that pajamas are the best option.

You can ask your friends to wear t-shirts of the same color and order the same pajamas for everyone. It will look very good in photos, plus your friends will have a very sweet memory of this day. When my sister was getting married, she found a site called what to wear with mom jeans and read that jeans and a white shirt would look good. And before the wedding, she had such a photo session; it looked very cool and stylish. So you can experiment.
