Hi! Normally I come to the boards as a way to relax after work (I own a bridal shop!), but since you asked I will tell you what I would say if the two of you were shopping at my store. Please understand that all of this will be guess work, cuz I'm basing it on the pictures.
1--Both bodices need some adjustment. Dress 1 needs to come in from the waist up; dress 2 appears to be sliding down at the top- needs to fit so that bust darts match up with the bust line, and no gapping at the sideseams.
2--Can dress 1 be worn without the extra crinoline? Many wedding gowns come with at least some petticoat already built into the dress. If your fiancee is concerned that she feels overwhemed in this gown but likes the overall style, try it again either without the crinoline at all, or with a less full version--crinolines come in many different sizes.
3--The flowers on the skirt on dress 2 need to be either re-worked or repaired. If they are being repaired, this should be at the shop's expense, not yours.
4--Be careful about adding/changing things on the gown. This will almost definitely add to the cost of the dress, sometimes significantly. If your fiancee is not in love with either gown, keep looking!! Tell your consultant what you like about each dress, and ask if there is a gown that combines the design elements she loves. And remember--it's a lot harder to find a good man/woman than to find a good dress!!
