What to wear for a friend's wedding?

In a few hours I will be attending my friend's wedding reception. She's a dear friend of mine whom I used to be bestest friends with in junior high. I'm honoured to attend her wedding and see what makes her happy.

However, I don't know what to wear. Actually, it's more like, I know I can wear something but I really don't want to wear it, because I have worn it to one wedding before, and another event already. I feel like I only have one dress to wear to formal events like weddings and corporate parties. It's accurately true.

I've been wearing this blue dress all the time. To be honest I only bought it because I had a 60% off coupon, and well I liked the A-line image it produced when I wore it. My pet peeve about this dress is that it shows way too much shoulder. It's one of those dresses that look really nice unworn, but when you put it on, it might as well look like a tank top dress.

I first wore it to my friend's wedding reception, with gold heels. I liked my outfit at that time. It was the Summer, so it was a perfect choice.

Secondly, I wore it to a corporate holiday party. Same style again. Even though it was winter, I still pulled out the gold heels.

Now yesterday, I did go dress shopping, but I bought casual dresses. They were cheap, what was I thinking? I should have purchased a formal/semi-formal dress to wear for a number of occasions.

I have an abundance of casual dresses, but of course I don't want to come under-dressed for a wedding.

I figured, I'll just wear my blue dress again, but this time instead of gold heels, I will wear black wedges. I thought about wearing tights, but honestly the dress is long on me... so tights would seem very out of place.

Technically, this is the third time I'd be wearing the dress, so I guess it's no biggy. In the future, I will take what I've learned and purchase some nice but affordable dresses that I could only wear a formal events... I have waaaaaay too many casual dresses!

I have one friend who I have never seen reuse a single dress. She always has tons of different styles. I could quickly go out and purchase a dress right now, but whatever, I'll do that later. The black wedge combination should look good. If not, then I can always go back to the gold heels. :)
