I currently wear Double Wear by Estee Lauder in shade IVORY BEIGE but need more coverage as have a very annoying blemish on my nose which never seems to stay covered. I've been recommended the Estee Lauder camouflage foundation but just need some advice as to what colour to buy which is the nearest to the IVORY BEIGE Double Wear shade I currently wear. I can't get to a store to check as live too far away so just need to know what the closest shade match to my current one would be. Thank you!! I really hope someone can help me out!
