I think you're right about the wanting more and more!
The poppy (I think some might have referred to it as 'fire') definitely has coral/orange undertones... I would probably describe it as a tangeriney-red. With that said, it would coordinate fantastically with corals, an outfit with some pastels and maybe vibrants thrown in, all white, all cream, greys, the list is endless I guess! ..Do you tend to wear brighter colors during the summer? I'm picturing a pair of your jeans in a dark skinny denim, cropped at the ankle, with a silky white or blush top and the poppy sandals.
The decision you make may be impacted by the city you live in. If it's miami.. I would say choose poppy and don't look back! I absolutely love the effect of the straw patent but the regular patent is just delightfully glossy and a bit more "classic." One thing I will say, you will never regret getting them in black! But you may regret missing out on the poppy!
