It helps to keep several spare light outfits on hand, not for a new look every day, but because heat and humidity mean more changes. Bali runs close to 80% relative humidity year round, with daily highs rarely below 28C according to the World Meteorological Organization. A baby in that air may need more than one outfit change before lunch. If you're packing for a trip rather than stocking a drawer, how many outfits to pack per day for a baby walks through the math in more detail.
The fabric matters as much as the count. Muslin cotton is woven loose and open, so air moves through it instead of trapping heat against the skin, and it dries fast after a wash or a sudden downpour. Epic's pieces are double-layer muslin cotton, pre-washed before they ship so they arrive soft instead of stiff, so they are soft from the first wear rather than stiff out of the package. Whether you still want a first wash at home is personal; wash new baby clothes before the first wear walks through what to consider. The seams are sewn flat and the dyes are chosen to be gentle, with no harsh finishes added afterward. Expect some creasing straight out of the bag. That's just how a loose, untreated weave behaves, and it softens with every wash after that.
Because you'll be washing often in a hot climate, stick to a cold, gentle machine cycle, then either tumble dry on low or hang the pieces in the shade. Skip fabric softener and high heat; both wear down a loose weave faster than normal use does. For the exact setting to use, whether muslin baby clothes can go in the tumble dryer has the detail. Vanessa and Bob design the collection in Bali, and sizes run roughly newborn through 4 years. Shipping is worldwide with tracked delivery, and any unworn piece can be returned within 30 days if the fit turns out wrong.
