At the wedding I did in January, I wore black dress pants with a nice dressy purple top. The bride's parents even commented on my professional attire and that it was very appropriate for the wedding. For shoes I wore my Dansko Cabrio clogs....I absolutely love these shoes! For those who haven't tried Dansko shoes and are looking for something dressy, comfortable and good for your back...you must try these! I am a respiratory therapist that works 36-50 hours per week doing 12 hour shifts, and I swear by these shoes. They are pricey ($120) but they are well worth it and will last you for a long time.
Just my opinion!
