Harold's is quite the New Haven institution if you ask folks who've lived here all their lives. It's where you go for your wedding dress (unless you're one of those people who goes to New York, or has a mother who sews). So, I took their advice and checked it out when I needed a wedding dress.
I lucked out and accidentally made my dress viewing appointment the day that they started their annual sample sale, fell in love with the first dress I tried on, and took it home with me that day. If you're not quite that easy to please, it looked like they had a great selection and very reasonable prices.
I also used them for my bridesmaid's dresses, and rental tuxes for groomsmen - the sales staff was very helpful and kind and cheerful, and their selection was extensive. Best of all, when my mother, six weeks before the wedding, announced that she hadn't yet bought a dress of her own, they jumped into action and helped her find something great (and very skillfully talked her into the right size - even though she insisted she was a size 8 - and the appropriate, structured underwear) Three cheers for their professionalism and good humor - which I think counts for a heck of a lot when you're dealing with a potentially stressful situation!
