The following are not in any specific order and were made with ShopLook (because rest in peace, Polyvore). Since I come from a more modest background, I made the looks in such a way that pairing them with sleeves, tights or a cardigan would not look bad.
This look simply requires a striped dress (preferably a maxi-length or slightly longer than a midi-length), a tote bag, a pair of sandals and some cute, but simple jewelry.
This look requires a skirt (the same length as the dress above), any matching top, a scrunchie (or any slightly fancy hair accessory), a long necklace and a pair of flats.
First of all, these boots are my life; I don’t have them in the same color but I bought a white pair from Zara and I absolutely love them. This look requires fancy sweatpants (or any other formal pants), a simple T-shirt (which can be tucked in), a pair of heeled boots, a matching handbag and a watch.
This look requires any midi-length dress or jumpsuit, earrings (hoops would look nice), a watch, a long-handled bag/purse, a pair of (slightly fancy) sandals and a sun hat.
This is just to make any casual outfit look trendier; match any t-shirt, jeans and shoes with a fun pair of sunglasses and a shoulder bag.
