Start with a pair of jeans that you already own and you've saved your self $20-30 right there. You can find some 3/4 length sleeved shirts almost everywhere, don't like the navy blue? That's okay, I personally would prefer red, especially with the leopard print heels! Forever21 has a few different styles 3/4 length shirts for under $15 and Target does too! As for the vest, you could go for a simple draped vest like this one for $15 or you could go a bit chunkier like this one for $22. For the bag you could do a plain black bag that most girls have already, or you could grab one anywhere for under $20. The shoes might be the most expensive for this outfit, I found some flats for $15, some wedges for $28 and some heels for $30.
Depending on what you choose for your outfit this could be as cheap as $65 or as expensive as $87 depending on if you need to buy the jeans of course. Pretty good for an entire outfit.
See you next week!
