Frequently Asked Questions

• How do I find my size?

  Our pajamas are generally true to size, though fit preferences vary. We recommend checking our Size Guide for measurements, model reference info, and postpartum/pregnancy notes.

• How do the tops fit?

  Our tops have a forgiving, relaxed fit through the midsection and a slimmer fit through the arms. If you prefer a looser feel in the arms, we recommend sizing up. For sleeveless and tank top styles, the fit is more flexible and most customers find their true size works great either way. Our fabric has a good amount of stretch and is not designed to cling.

• How do the bottoms fit?

  Our pants and shorts feature a stretchy waistband with lots of give and a relaxed fit through the leg. They're designed to be comfortable and non-restrictive — great for sleeping, lounging, and everything in between.

• I'm pregnant or postpartum — how should I size?

  If you're in your third trimester, we recommend sizing up one size to accommodate your bump comfortably. Postpartum, most customers return to their pre-pregnancy size — though if you're nursing and want a little extra room in the top, sizing up works well too. See the Size Guide for more detail.

• What's your return policy?

  We accept returns within 30 days of receiving your order on unworn, unwashed items. If something doesn't fit right or isn't what you expected, we'll make it right.

• How do I start a return or exchange?

  You can request a return through your account portal or reach out to us at hello@piperandmint.com and we'll walk you through it.

• Is there a fee for exchanges?

  Exchanges are subject to a $8 return shipping fee to cover the cost of your return label. You'll receive an invoice for that amount, which will need to be paid before your exchange order is sent out.

• What if my item arrived damaged or incorrect?

  That's on us — reach out at hello@piperandmint.com and we'll get it sorted quickly.

• How does mint-infused fabric actually work?

  Our fabric uses menthol — the naturally cooling compound in mint — woven into the fiber itself. It interacts with your skin to create a cool-to-the-touch sensation that doesn't rely on chemicals or coatings. It's not a scent or a spray — it's built into the fabric and lasts wash after wash.

• Will I smell like mint when I wear these?

  No — there's no minty scent. The cooling effect comes from menthol in the fiber itself, not a fragrance. You won't smell like a candy cane, we promise.

• How long does the cooling effect last?

  Our mint-infused fabric has been tested to maintain its cooling and moisture-wicking performance for 50+ washes. With proper care (gentle cycle, low heat or air dry), it'll stay effective for the long haul.

• What exactly is the fabric made of?

  Our signature fabric is 66% Lenzing Modal, 29% mint-infused viscose, and 5% elastane. Soft, breathable, and with natural stretch — designed for real sleep.

• Is this fabric safe for sensitive skin?

  Yes. Our fabric is free from harsh chemicals and gentle enough for sensitive skin. The mint component is derived from natural menthol and doesn't contain irritants. You can find full fabric details on our Benefits page.

• How do I wash these?

  Machine wash cold on a gentle cycle. Tumble dry low or lay flat to dry — this helps preserve the fabric's cooling properties and softness over time. Avoid bleach and high heat.
