I think that Forever 21 has seriously improved their game lately with the diversity of items they’re offering … you didn’t used to see dresses like these there very often.
My latest favorites …
This polka dot belted skater dress
This abstract pattern lace dress
This cutout neckline belted dress
This pleated flounce trim dress
This belted skater dress
This studded collar a-line dress
PS – they’ll ship orders of $50 or more to you for free.
