I’m 19, my boyfriend’s (he’s 21, been with him for almost a year & ½ – totally in love) sister is getting married next weekend…I have a chic, black, sweetheart style, strapless, A-line dress that I’m going to wear with black stilettos. It looks good but it’s kind of plain. SO I bought some faux pearl necklaces to layer, a couple small pearl bracelets, a medium size faux, antique like, diamond-y ring, and some faux diamond stud earrings….It all looks really cool….I’m just really afraid that it will be TOO over the top…I mean, it’s a pretty "fancy" wedding I guess, but its not Prom or anything…What do you think??
I’m pretty close with the family – but I’ll be meeting ALOT of out of town relatives and friends who I want to make a good impression on! HELP! 
Oh yeah, and the wedding is at like 6:00pm…
The dress lenght is like 1 1/2 or 2 inches below my knee…
When determining what to wear to a wedding, it is important to look at the time of the wedding. If it is an evening wedding, then the traditional attire would be formal. What you are wearing should be fine in that case. If it is a day wedding, you are probably going to be a little bit on the formal side.
I would ask your boyfriend’s sister if she thinks this outfit is appropriate if you have any doubts. I am guessing she will think that it is fine. You can never go wrong with basic black. If you get there and feel over dressed, you can always take off some of the jewelry.
