The shades online look very confusing to me. Using the hosts/models didn't help matters, but increased the guessing game for me.

The Tan online looks very light, yet they claim that's what Brenda the model is wearing in this photo. Brenda's natural complexion is darker than Leah's. Yet they have Leah in Rich, which still looks far too light for Leah; she may be wearing it, but it looks like a terrible match. Then they skip several natural skin complexions to get to Jayne Brown wearing Deep.
I'm about Leah's true complexion, but I could never match with Rich or Deep.
I would not know what shade to get. I don't think much effort went into trying to truly get good foundation matches. It'll be a day of, hearing "don't over-think the shade!" That's an instant turn-off.
Pass.
