I'm a huge fan of the 3/4 length sleeves. We were married in November and I was planning on having a very cold wedding. Thankfully, we were blessed with a miraculously warm day (in the low 60's when it had been snowing just a week before,) but I think that even if we'd been married in the summer I would still have kept the longer sleeves.
I love this dress, but I didn't want to transport it across the country to our reception in Michigan, so I wore my "Getaway Dress" (which was my maternal grandmother's wedding dress) at our other receptions. To see my post about that dress, click on the picture below!
