Traditionally, white tie attire for women stipulates that a ball gown which exposes decolletage must be worn. Evening length gloves are also required depending on the event, and tiaras may be worn by married women only. In a modern context, white tie for women requires a ball gown.
When it comes to smart casual for men, go for casual trousers such as chinos or suit pants. In summer, you could even wear shorts. They can accompany their trousers with a long-sleeved shirt, and an optional jacket and tie. If you must wear denim, go for the stylish dark blue, tailored type.
Of course, I think digital files are also really important at this point in time. They’re wonderful for sharing with friends and family all over the world instantly. I always include digital files while the album is optional, so you can use those files to make as many of your own prints as you like anyway. But I love albums. There’s nothing like seeing your beautiful photos printed out in a way that lets you actually physically hold them.
