I did look at various dresses online and even printed some off as an idea but in the end didn't even refer to it
. I'd requested one dress I wanted to try on in particular which they had to bring in from another store and that one turned out to be the one I went with! But in the end I just went round and picked some to try on and made sure I tried on a variety of styles in case I liked something different to what I thought! Good luck for dress shopping and enjoy it! I found it such fun!
Oh and as for underwear I just wore a nude strapless bra with nude knickers. On the day I will just be wearing knickers as the top of my dress is fully boned so like a corset in itself
. I am a bit nervous about being seen half naked but needs must I guess!
