I don't know the Varvatos scent unfortunately, but here are some recommendations for orange scents:
Hermes - Eau d'Orange Verte: a bitter orange scent, sharp and refreshing, a great summer fragrance
The Different Company - Bergamote: exactly what the name says, another great summer scent
Fendi - Theorema is a warm, spicy orange scent with a burnt facet (if you can find it).
You can also try to use unscented body cream, let it sink in and only then spray the scent on, it can increase its longevity. Using the matching lotion is also a good idea. In case you haven't done it yet you can experiment with more spritzes (I normally use some 8 to 10, except for really heavy scents).
