My top summer fragrances from these are the two Marc Jacobs fragrances. You may well ask the question as to why I would have two of the same variant (in Marc Jacobs Daisy and Daisy Eau So Fresh) but the two do have some differences. For me, Eau So Fresh is a more long lasting and summery fragrance than Daisy is. Daisy is perfect for those not so hot but sunny days whereas, for me, Eau So Fresh is more for the very summery days.
Either way, I love both.
