Hi Chijmes,
When I went to try the Wedding Gown, I only knew that I liked a few designs from all the bridal magazines that I've read. So be selective, have an idea of what you what. Some questions you may want to ask yourself to help you narrow down your choices:
a) What colour do you want? (White or Cream)
b) What type do you like? Have at least 2 choices just in case.(Tube / Off shoulder / Halter / Toga / U-neck / Square neck / ...) You more or less know which you look great in and so it's best to stick to it.
c) Where do you want to emphasize? (The front design or the Back design - i.e. the trian) *Very Important question - WL will use that to select the gowns for you to try.
d) What type of design do you like? (Lace / Embroidery / Plain / Big floral prints / Small floral prints / ... )
Okay, these are all I have. Hope it will help narrow down. Just to share, my personal favourite was the one from Divine Coultre, the bareback with lace as the attached string, the gown that had been advertised in SB for some time. So I more or less have an idea but I did not stick to it. I gave the ladies at WL the flexibility of selecting what they thought looked good for me, then when I started to reject, they more or less know what I wanted (cos my mind wasn't that clear at that time too ... too nervous, excited and all la). Towards the end, I realised the gown I wanted had that floral pattern similar to the one I saw in the advert.
As for EG, I can't really help you. Only know that you must first select the colour. Then after that, she will show you all that she has of that colour. Have a second choice of colour. Otherwise sure stuck. I will be looking for more EG designs too.
