hey! i can recommend you two brands to lookout for online. browse through their site and you might come across something you like!
Steve Madden (click here for the link straight to awesome sandals!)
Tory Burch (www.toryburch.com) this was one of Oprah’s favourite things for 2010!
these above are all on the upper or mid range shoes prices. however if you want to spend minimum, don’t be afraid of trying normal online sites and if you’re worried they might not last the entire trip, BUY TWO for a variety too! you can try some of these websties for lower price range.
Urban Outfitters (click here straight to flat sandals!) this website has awesome collection of clothings too!
ModCloth (click here straight to flat sandals!) for mod, vintage retro inspired clothings and shoes!
GoJane (click here straight to flat sandals) cheap priced shoes here!
Forever21 (www.forever21.com) big retailer with cheap range of clothings/shoes/accessories.
ASOS (www.asos.com) Located in the UK, online retailer with huge base of brands and fashion items.
i hope all this will help you! have a great time in Italy!
p.s Italian leather is famous too! will be a great place to scout for unique buys and vintage goods!
