First I'm going to start with actual Wildfox that i found for cheaper than the normal $108. In case you didn't already know this, Ebay is a great place to check! http://compare.ebay.com/like/380389732230?var=lv<yp=AllFixedPriceItemTypes&var=sbar&_lwgsi=y <--- This is a link to a Wildfox Couture Sparkle Heart Baggy Beach Jumper new with tags on ebay for only $94 (If the shortcut doesn't work then just copy and paste!) While that still is quite a lot of money, if you are looking for an authentic one, it won't get much cheaper! If you go to that page and scroll down it will show other options on ebay too, but it won't go below $90.
Here are some look alikes that i found (PLEASE keep in mind that they won't look exactly alike, just similar.)
Here is our first adorable look alike. It is from Modcloth: http://www.modcloth.com/shop/sweaters/glitz-i-adore-top (again, copy and paste if needed). This is quite a steal, at only $34.99! I was going to order this exact piece once i found it, but my size is sold out. Also, in the reviews it says order a size smaller than you normally wear because it runs a little large.
This one is also from Modcloth: http://www.modcloth.com/shop/pullovers-sweaters/deer-prudence-sweater . Now this might not be every ones cup of tea, i think its pretty cute. Sure, it doesn't look exactly like a Wildfox, but it's still cheaper at $72.99
This is yet another piece from Modcloth! http://www.modcloth.com/shop/sweaters/remarkable-top . This one really does look like it could be a Wildfox original, but it is only $31.99! So much more affordable than a true WF!
This next one is from Charlotte Russe and is only $20.99! I love this shirt because you could easily dress it up or down, depending on your mood/occasion! Also, who can beat 21 dollars?! http://www.charlotterusse.com/product/index.jsp?productId=12149182&cp=4078198.11025267.11589628
A great steal from Forever 21 for only $17.80! http://www.forever21.com/Product/Product.aspx?BR=f21&Category=sweater_other&ProductID=2078818236&VariantID=
Make sure you look at the options on the righthand side of the page once you go to this link because it shows other similar ones!
Now this really does look like a Wildfox! And who wouldn't love this adorable jumper for only $17.80? Order yours now: http://www.forever21.com/Product/Product.aspx?BR=f21&Category=sweater_other&ProductID=2008584984&VariantID=
I just love how F21 paired those last two options with colored jeans! Colored jeans are a must have this season!
This sweater is from Wet Seal and is only $22.50! It is super cute and would be the perfect addition to your wardrobe this winter! http://www.wetseal.com/catalog/product.jsp?categoryId=215&productId=52985
