On the left we have Betsey Johnson's Burnout-Dots Halter Dress for $325.00 at Macys.com.
It's sickly sweet, so much so, that you just might tire of this cute little number after one season.
If you're feeling like Strawberry Shortcake, go for the dress on the right, Heritage 1981 Polka Dot Dress for just $20.00 at Forever21.com.
The dress from Forever21 is just plain better anyways: It's longer (37" vs. 27"), made from 100% cotton and you can actually wear a bra with it. You could also layer with the dress from F21, not the one from Macy's.
Both have delightful ruching at the bust, both feature a ruffled hem and both have those irresistible polka dots—but only one has a lovely price tag to match.
