For the majority of trips I’ve taken, I have used a formula that has been dependable for packing. The five pieces I always pack in my suitcase are: trousers, a sweater, a blazer, a white shirt and a black dress. I can mix and match these pieces, swap out a pair of jeans for the dress if the trip is all casual, and of course add accessories to any combination to mix up the colors. If the weather is warm, shorts and a T-shirt might be added, if the weather is cooler, a heavy jacket and a scarf. Add to these pieces the appropriate shoes, boots or sneakers and you have a simple formula for a capsule wardrobe when packing for almost anywhere.
My go-to shop for travel wardrobe is my local Theory boutique. I can always find these pieces in a variety of neutral colors for any occasion. In fact, when I look back at pictures from my trips, I can tell you my exact location and what year it was based on the outfits I am wearing. I went to London and sailed back on the Queen Mary 2 with a suitcase of tan and burgundy. I went to Paris (the first time) with a suitcase full of navy and black. I was planning a trip in spring of 2020 with a suitcase of French blue and white – I will use that capsule soon, I am sure of it!
These are my favorite trousers from Theory:
