black mini shift dress PrettyLittleThing Women's Trim in breathable linen Women's Scoopneck Mini Shift Dress

Light grey pants with white sneakers look clean and casual, while dark grey pants feel sharper

This is a great way to add a playful feel to your outfits without adding a bright color or daring pattern

Designed for the daring fashionista, this dress combines a fierce leopard print with a sleek backless design, making it perfect for turning heads at any event

Also, I'm planning to buy the burgundy dress and it mentions that I can customize the color of the ties (as red probably wouldn't look good) what color would you suggest

Also to the comment about black jeans I have no idea, but the standard black and white converse shoes are probably the best I have managed
