Planning a wedding is fun and stressful at the same time with so many things to consider. If you are still undecided about the bridal party wear you should consider try the mix and match look.
You would need to choose the main colour and to play it safe preferably a neutral one.
The maids can then choose their favourite shades to mix and match. However if you choose a solid colour do make sure each girl choose their own neckline- halter, strapless, off- shoulder etc. The girls can also have different hairstyles and accessories as per their liking thus maintaining their uniqueness.
