“They’re literally my favorite piece of clothing I own, and they’re so affordable!”

"A couple of dresses: really like pinafore dresses because they can be layered depending on the season, also a few good cotton shirt dresses for summer. 

A couple of slim wool turtlenecks for winter layering (I get mine from Muji). 

A couple of low heel pointy toe pumps, they make anything look workwear-ish even if it's big and baggy."

"My tiny trick for stopping an all-black outfit from feeling too serious is colorful socks. Barely there, but it does the job."

"That, and some really comfortable heels. I'm 5'0 and wearing block heels really does make a big difference to how my entire outfit looks. When I say comfortable, I also mean I can walk for 30 minutes, no problem."
