It seems like a silly question, but do you want your bridesmaids in identical outfits? Maybe if they are all a similar height, age and build, but that's unlikely really. So what are your options?
You could get a dessy twist dress for each bridesmaid, and leave the rest up to them.
The dessy twist comes in a rainbow of colours, and can be twisted into loads of different styles, including a skirt!
Another option is to get strapless dresses, and have them customised for each bridesmaid, using lace or mesh to create straps or sleeves.
Many brides choose bridesmaid dresses from high street shops or department stores, who often sell different styles of dresses in the same fabric. Debenhams, New Look, and website Chi Chi London have an excellent selection of gowns which can work for bridesmaids.
If you are on a budget, BHS sell a wide range of dresses from flower girls up to adult bridesmaids, and with matching colours throughout.
If you're not like the "completely matching" bridal party, why not choose two colours to complement your theme. That way, bridesmaids can choose a colour they like, or older bridesmaids can wear one colour, and younger bridesmaids wear the other.
A new trend is having bridesmaids in lots of different shades of the same colour, which sounds and looks amazing, but I'm guessing it would be difficult to plan.
Some brides just ask their bridesmaids to choose their own LBD. That way, they can have one in their own style, and it can be worn again after the big day.
Also, you might want to consider putting something slightly different on your Cheif bridesmaid/ Maid of honour to make her stand out a little.
One of the most important things to consider is your budget. Traditionally, bridesmaids pay for their own dress, but a lot of the time, this isn't the case. Bridal boutiques custom make gowns, but this is very pricey, and alterations aren't usually included. If you have a huge budget, this is the option for you.
Debenhams stock a range of Jenny Packham dresses which are beautiful, and ideal for bridesmaids, but are a little more affordable than ones from her bridal range.
Ted Baker and Coast offer affordable luxury dresses which will be loved for ever, and could even double as a gift for your bridesmaids if you're stuck for ideas.
High street stores including Quiz and even Tesco have beautiful affordable dresses. It's definitely worth checking out every option before buying, you never know where you'll find the perfect dress.
Beware of online shopping, and make sure you are aware of returns policies in case products are unsuitable. It may be tempting to order from eBay sellers in China, but check sellers feedback, and always interact with the seller before purchasing, and check on any extra fees in tax that you may have to pay.
