Hey ladies..we are lucky enough to provide our own alcohol, saving us a ton of $. I am going to order personalized cups for the reception but am not sure what sizes to get. We need 3 sizes...one for our signature cocktial..one for wine..and one for beer...this is what I was thinking Wine- 5oz Signature- 8oz Beer- 10 oz I am hoping to somewhat be able to tell how much to get of each based on the sizes of the cups. Opinions? Thanks!
