How can that be possible?
The trendy pieces are not priced low. A little creativity and time can help up to do that. We can carefully search the thrift stores to find those right pieces. Cosmetics can be found cheaper too. Adjust the jewelries to suit with the outfit and can have your own style.
With the help of internet DIY tricks, you might be able to make hoes in your jeans to get that look.
Those are all personal choices.
