It is so important to bring a few options with you to the photo shoot. Have everything pressed and ready to change into.
If you are doing a 20 minute shoot with your team, make that wardrobe change easy! Could be as easy as a tie or different coat. Blazer changes are easy as well as necklaces and earrings. For longer private shoots the wardrobe changes can be more extensive! Either case, make sure it all fits well and you are very comfortable in what you are wearing. Normally I will have time to show you a few shots so you see the results.
As far as color I would try to stay away from matching your skin color. Send me a selfie and I’ll help you choose colors!
