thanks for your reply liberty! but i considered that, and the description on both sizes reads, "eau de parfum spray", and that (at least to me) indicates that the concentration, or strength, is the exact same---that's why i was (am) confused-- i would prefer the more concentrated, but no variation of concentration was indicated. anyhow, thank you again! i'll just return it if it's weak :)
It's not about the size of the perfume it's about the concentration. The one once bottle is concentrated and stronger than the 1.7 ounce bottle.
