At Olive Basics, we have dual size labels, e.g. XS/S, S/M, M/L—not to confuse you, but to help you find the right fit more realistically.

A size label is fixed, but a good fit is not. Especially as women, it is possible to go through weight fluctuations throughout the month, or have changing bodies through seasons of pregnancy, postpartum or breastfeeding. Remember that a size label isn’t universal—it’s shaped by manufacturers, and depending on the fabric, cut, and how you like your clothes to feel, you might find yourself wearing different sizes across brands or even styles.

Take note of our product descriptions and fit notes, and think about how you like to wear your clothes—snug or relaxed—to find the best match. Still unsure? We’d love to help. Chat with us on our website or DM us anytime at instagram.com/olive.basics

Each product page includes a size chart with measurements to help you find your best fit. If you’re in between sizes, we typically suggest sizing up for a more relaxed fit, especially for styles with built-in support.

Still unsure? Feel free to reach out, we’re happy to help guide you.

Many of our styles are designed to adapt to changing bodies and life seasons, including pregnancy and postpartum. You’ll find discreet openings, stretch-friendly fabrics, and thoughtful silhouettes across our range without compromising on style. Feel free to check out our Maternity collection.

Select styles include built-in shelf bras or removable padding to make getting dressed simpler. We always list these features on the product page, so you’ll know exactly what to expect. If you prefer added support without extra layers, these pieces are especially made for you. Feel free to check out our Padded collection.

Most pieces can be gently machine-washed. Just use a laundry bag, cold water, and skip the tumble dryer. Hang or lay flat to dry, and avoid bleach or harsh detergents. Our fabrics are designed for daily life, not delicate handling, but caring for them well helps them last longer. Expect a little softening and character over time, that’s part of the charm.

Our pieces are designed to move with you and hold their shape through regular wear. That said, natural wear and tear is to be expected—especially with softer, more breathable fabrics that aren’t coated or synthetic like polyester. Hang to dry and avoid tumble drying to help preserve the fit and finish. These garments are made to be lived in, not kept pristine—and we think that’s a good thing.

Yes, our fabrics are chosen with comfort and performance in mind. Many styles feature breathable blends that help regulate temperature and resist wrinkles, making them perfect for daily wear or travel. Each product page highlights key fabric benefits so you can choose what works best for you.
