Hi Nutella,
I have a couple of options:
. you can colour co-ordinate with a blue crystal jewellery & hair comb/hair pins, (on my site is a Swarovski colour chart page so I can create any of my designs using the crystal colour chosen to match your dress)
. simple white pearl jewellery and hair comb/hair pins,
. clear AB crystal jewellery & hair comb/hair pins.
Here are some of the examples of my pieces:

Crisitina Fuschia comb or Dana crystal hair pin (can be created in clear or blue crystals)
Ideal with:

Eve necklace & earrings (can be created in clear AB crystal or blue crystal)
Both can be incorporated into side hair dos and up dos. I particularly like side dos with a row of hair pins or a comb, similar to this:

I also have pearl & crystal hair combs:
Anna gift set - available with hair comb/hair pins, bracelet & earrings
Silvia Gift Set
Here is a link to my bridesmaid gift set sections. The sets can be tailored to your requirements too - so if you wanted a comb and earrings, I can create a set purely for what you want.
Feel free to have a look on my site www.simplysilverbridalprom.com and drop me an email: rperrin28@yahoo.com if I can help you with anything.
Regards,
Rebecca
