Thanks to a lovely follower on Instagram for informing me that my favorite 'Poppyy' flats are back in stock in smaller sizes (starting at size 5) at Nordstrom! Now if only they would go on sale because they're spring/summer flats and it's already boot season. My favorite pair of all the colors is the black and white version since it reminds me of the popular Chanel flats but for a fraction of the cost. I personally found that these run about a half size larger but the size 7 works for me with plenty of space in the front for my toes so I could probably take these in a size 6.5.
My friend Thu also showed me a similar, quilted pair from Macy's called 'Passion' yesterday and upon further research I also found a similar style called 'Portia'. Links to the same and similar styles below.
Update 5/15/15: There's a similar, Target version here as recommended by My Girly Armour.
I'm also love this cute canvas pair from Aeropostale.
