Grooms-women's attire?

They should wear whatever they're comfortable in. It could be the same suit as the groomsmen or dresses in complimentary colors.

My husband had his two sisters as groomswomen. They wore black dresses and the groomsmen wore black tuxes. My bridesmaids were in gray dresses.

My sister had a similar situation for her wedding. On her side she has a friend who preferred to wear a suit and the suit matched the bridesmaid colors in blue. And on the other side they had both suits and dresses in black. Have them wear whatever is most comfortable for them in a suit or dress, but having them match their side of the party.

I think putting them in similar dresses of a different color would be nice!

My FH has a female on his side and she is wearing the same suit as the men. BUT that was her choice- I told her either that or a dress in our color swatch would be good.

I like it when they match the bridesmaids and don’t have to wear a navy or gray dress, but I guess that’s just me. I wouldn’t ask them to wear suits though unless that’s something they prefer.

Unless either of them are more comfortable wearing suits and not dresses to formal events I wouldn’t have them wear suits. I would have them wearing a color that matches or complements the GMs. For example my H had a groomswoman, his guys wore burgundy ties so she wore a burgundy dress. My girls wore mocha dresses and mustardy gold wraps, so she clearly matched with the grooms side and not the brides .

I think you should ask them first as they might not be comfortable wearing suits. You can definitely have them in dresses the color of the guy suits or another color from your color palette that is different than your bridesmaids.

On H's side he had a Best Ma'am. We asked her if she'd want to wear the same thing as the rest of the groomsmen or if she'd want to wear the same dress as the bridesmaids but in H's color. She opted to wear the same thing as the groomsmen, but then she did end up changing into a green dress at the reception.

I think it's best to ask what they're comfortable with first and work from there.

My FHs female cousin will be a groomswoman. I just asked her what she'd be more comfortable in. She is opting to wear a dress. It will be a similar style to my BMs, but it will be black to match the GMs suits. We'll give her a colored sash or something to match the guys' ties and pocket squares--which will be the same color as the BMs dresses.

My FH has two women standing with him. They both decided they’d rather wear dresses. They have navy dresses and the men will wear navy also. They are similar in style to the bridesmaids dresses but different colors.

My FH has his sister and best man wearing the same suit. They’re going to alter the suit to fit her body

I think that they should wear a suit/dress depending on what they're comfortable with, but should definitely match the groom's side opposed to the bridesmaids.

My FH has his two sisters on his side and they are wearing navy dresses to match the groomsmen's navy suits.

In the most recent wedding we attended, the groomswoman wore the same color as the bridesmaids. In a previous wedding, the grooms woman wore a gray dress (men were in gray suits).
My MOH is wearing a suit because that’s what she’s most comfortable in.
I would have them wear what they’re most comfortable in.

Their dresses should be the same color as the groomsmen. I have also seen grooms-women wear jump suits, also in the same color as the groomsmen's suits or tuxes.

Thanks for all the help! I will ask what they would like to wear, but will probably have them in the same color as the groomsmen.

My FH has a groomswoman, she’s going to wear the same dress and same color as the bridesmaids and she’s going to walk in with the bridesmaids, her only difference would be going to stand behind the groom after the procession

My FH's sister is a groomswoman and is wearing a navy dress since the men are wearing navy pants.

Do whatever you want (and what the grooms-women are comfortable with)!

I suggest dresses to match or compliment the suits or a jumpsuit in a color to match or compliment the bridesmaids dresses. For example, if your FH and his groomsmen are wearing a navy suit and your bridesmaids are wearing blush dresses, I'd put the grooms-women in a navy dress (or jumpsuit) or a blush (or perhaps dusty rose) jumpsuit. That way they will stand out from the bridesmaids but the entire look will still go together.
