Most people pack too much swimwear and not enough lingerie, or the reverse. The question of how many pieces to bring is less about the length of the trip and more about the type of trip. A week in Okinawa with daily swimming is different from a week in Kyoto with one afternoon at a ryokan pool. Getting this right before you pack means you bring less and use everything you bring.
How many swimwear pieces do you actually need ¶
For a trip with daily swimming, two swimwear pieces is the right number. One dries while you wear the other. Three is comfortable but rarely necessary. One is fine if you are disciplined about rinsing and drying, but a single piece that does not dry overnight becomes a problem on day three. For a trip with occasional swimming, one piece is enough. The Hayama One-Piece is the piece we recommend for a trip where you want one thing that works in the water and looks considered out of it.
Packing without crushing delicate fabrics ¶
Swimwear can be rolled tightly without damage. Lingerie should be folded flat or placed in a small cotton pouch. The Daikanyama Silk Slip can be rolled loosely around a pair of shoes to save space and protect both. Do not pack silk or lace at the bottom of a bag under heavy items. The pressure does not damage the fabric permanently, but it creates creases that take time to fall out. A hanging toiletry bag with a flat pocket works well for lingerie.
Caring for pieces while travelling ¶
Rinse swimwear in the hotel shower after each swim. Most hotel bathrooms have a towel rail that works for drying. For silk and lace, a small bottle of pH-neutral travel detergent is worth the space. The Enet detergent we mentioned in the silk care guide comes in a 100ml bottle that fits in a liquids bag. Hand wash in the basin, roll in a towel, hang to dry. A piece washed this way every two or three days will last the trip without degrading.
What to do if something snags or tears ¶
A snag in lace or silk is not the end of the piece. As described in the silk care guide, a blunt needle can push a snag back through to the wrong side. For a tear, a small piece of iron-on silk repair tape (available at most fabric shops and some pharmacies in Japan) can hold a seam until you get home. We keep a small repair kit in the studio and can advise on specific repairs if you write to us after a trip.
The case for bringing fewer, better pieces ¶
A trip with four swimwear pieces and six lingerie sets means six days of laundry decisions and a bag that is heavier than it needs to be. Two swimwear pieces and three lingerie sets, chosen to work together, means less weight, less decision-making, and more room for things you buy on the trip. The styling consultation is specifically useful for this kind of planning. Aiko has helped several customers pack for Bali, Ishigaki, and the Maldives with fewer pieces than they expected to need.
Packing well is mostly about knowing what you actually use versus what you bring for reassurance. If you want help planning a specific trip, the styling consultation is a good starting point.
