i like 'em both! i think trying colorful accessories with the polka dots can be a lot of fun (periwinkle, cobalt, citron, tomato) - you can even try zebra print if you're feeling wild! at the same time, with 'traditional' accessories (pearls, heels, etc.) you could dress it up for professional or more formal occasions. nice!
i like the first one a lot! those colors are gorgeous with your hair and complexion...and the loose shape makes a lot of sense in the heat while showing off your shoulders and legs at the same time (avoiding any frumpifying). with hair and makeup, gold accessories, and a nice heel it would be perfect for a nice dinner out, as well - i don't see it as a 'strictly casual' look at all. so pretty!
i do wonder a little if you were smiling and standing more confidently or even wearing a nice heel if you/we might see the first dress more favorably....it reminds me of Angie's recent post on putting on makeup and doing your hair before trying new outfits. with 'old standby' types of clothing it's easier to visualize how it may look in a 'finished' outfit. but when we're trying new silhouettes, colors, patterns, etc. i believe that proper foundation garments, shoes, makeup, and so on can help us to see the piece's true potential.
i am in no way saying you should 'be a better model'! shooting myself for my blog, i know exactly how difficult it can be to pose for the camera - especially facial expressions. (blurgh!) but i have found that making that extra effort can help me to see the potential when i'm outside of my comfort zone or trying to push my style boundaries.
Hooray! two great dresses! and how much fun to be planning a cruise....yum!! have a great day, steph
