They have a special line that is dedicated to bridal stocking and tights and as a result stock everything. You can be sure that you will find what you need whether it is ivory sheer stockings and suspenders or just a simple lace garter.

The Psiche brand is my favorite which comes in black, white or ivory.  They are stay up stockings with 10cm of a luxury lace band around the top of the legs. For a Garter then check out the Fortuna garter which comes in white or blue. Remember something borrowed, something blue!. Still keep them in mind  for after your wedding as well as they also do a full line of pre natal stockings and tights.

Instead of limiting yourself to one piece be open to all the other lingerie alternatives on offer. A corset may not necessary be the right look for you, a body shaper will provide more of an effect. A lot of dresses will already have the corset and bra already built into it however if not then be careful to consider the right bra  and more importantly one that fits.

I also strongly recommend wearing the bridal lingerie for a trial run before hand. I bought a strapless bra for my wedding dress and more or less spent the whole day trying to keep it up. Other bras such as the stick on adhesive bras can loosen with sweat, so as you can see a trial run is essential.
