I always buy neutral colors (black, white, cream, tan, and all shades of brown and grey) that would suit my basics: simple tops, trousers, cardigans, etc. Make your outfit look 10x better with something as simple as adding a leather jacket or a nice cardigan, paired with some black or nude heels & simple jewelry. Try finding a pair of black or blue jeans that are comfortable and hug your body in the right way. And for date nights I suggest you get a little black dress and a nice pencil skirt with a button-up.
Is there a preferred method for tipping servers? Like, should I try to tip in cash, even if I'm paying for my service with a card, or is electronic preferable?
