How to Pack for a Trip When You're Between Sizes or Seasons of Life

Default to loose-fitting, multi-purpose clothes over rigid, fitted pieces, stick to a tight neutral palette, and separate categories with packing cubes, since packing gets genuinely harder when you're not packing for one fixed version of yourself.

Quick Answer

Why the Fix Is the Same Regardless of Which "In-Between" You're Packing For

Packing gets genuinely harder when you're not packing for one fixed version of yourself, whether that's a body that's changed recently, a wardrobe you're mid-transition on, or a trip that's going to move through several actual climate seasons before it's done. The good news: the practical fix is largely the same regardless of which kind of "in-between" you're packing for.

Loose fitting clothes should be the default, not the exception. Someone who packed a single suitcase for a full year of travel across every season, snow, extreme heat, rain, and back again, put it plainly: everything you pack should be multi-purpose, and rigid, fitted pieces are the first thing to cut. A structured blazer or a fitted dress that only works at one exact size or in one exact climate earns its space far less than a loose, adaptable piece that moves with you, literally, if your body is changing, and practically, if the week ahead swings between climates.

Easy-going clothes that don't ask much of you day to day matter most: dresses that work as both daytime pieces and evening options, tops that go from a co-working space to dinner, basics that layer instead of pieces that only work alone. The actual test worth applying to every item: does this serve more than one purpose? If a piece only works for one specific size, one specific season, or one specific occasion, it's the first thing to leave home.

Common Mistakes

People assume individually great pieces are worth packing even in bold prints. In practice, a tight, neutral color palette works better, a year-long traveler learned this the hard way, bright, one-note florals and patterns looked great individually but didn't mix with anything else in the bag, while a neutral base meant nearly everything she packed worked together.

People assume loose organization is fine when what you reach for might vary day to day. In practice, packing cubes organized by category, one for basics, one for anything warmer, one for anything you're not sure you'll wear yet, matter more here, since it means finding what actually fits and feels right today without unpacking the whole bag.

People assume more jackets and shoes hedge against uncertainty better. In practice, one genuinely good jacket that layers, and two or three shoe pairs chosen for function rather than each possible scenario, covers more real ground than a suitcase padded with backups for every version of you or the weather that might show up.

People assume packing for a hoped-for size or season is smart planning. In practice, packing for who and where you actually are on day one, with enough flexible, loose-fitting pieces that the bag still works if none of that changes by the time you're home, is the more reliable approach.

What to Prioritize Instead

The multi-purpose-item rule, the neutral color palette strategy, the packing cubes and category-separation approach, and the limit-heaviest-items guidance are all drawn from Alicia Briggs's guide to packing for multiple seasons, based on her own year-plus of full-time travel across every climate season.

Prioritizing what you actually use daily over what you think you might need matters too. For the traveler behind this approach, that meant a compact yoga mat and travel workout gear, not for a single day's outfit, but for the daily habit that mattered regardless of size, season, or location. The equivalent for anyone packing through a body or life transition might be the pieces that actually make you feel like yourself right now.
