Wedding guest style for her
* Informal Daytime: Short dress or suit (business attire OK for morning weddings)
* Informal Evening: Cocktail dress
* Semi-Formal Daytime: Short dress or suit
* Semi-formal Evening: Cocktail dress
* Formal Daytime: Short dress or suit. Hats and gloves optional.
* Formal Evening or Black-Tie: Long or dressy short cocktail (beading, glam accessories, wrap)
* Ultra-formal or White Tie: Long gown, extra glitz (furs, diamonds, etc.)
Do's and Don'ts for Her
* Don't wear white because it competes with the bride. There are plenty of other colors available.
* Don't wear black or sequins during the daytime.
* Don't worry about wearing the same colors as the bridesmaids or mothers. You can't possibly coordinate with everyone in the wedding party.
* Do wear something feminine and appropriate, out of respect for your hosts. Clubwear, overtly sexy clothing (strapless, see-through, etc) doesn't belong at a wedding. If you have to ask if it's appropriate, it probably isn't.
* Don't wear opera-length gloves (to top of arm) with anything but sleeveless or strapless gowns.
* Do take off gloves to eat or drink.
* Do use good judgment if the invitation doesn't specify the formality of the event. A pastel suit or soft floral dress for daytime or a little black dress for evening (after 6 p.m.) will take you almost anywhere.
I have that dress and hate it..the cinchy thing in the back is NOT flattering. i have no chest though (well I do now hahhaa) so that might be the problem before. Not sure how tall you are, but I'm 5'4 and it's SHORT.
I'd probably go for a tad longer dress and I'd be ok wearing black...
