Start with the fabric and care
The Short Sleeve Top & Boxer Set from Cosabella's Pima Lusso Printed collection is made from a 50% cotton, 50% modal blend. The fabric is pre-shrunk, breathable, wrinkle-free, and pill-resistant, which makes it more forgiving than untreated cotton. But the care instructions are specific: hand wash only and do not dry in the dryer. That's not a suggestion—it's how you keep the print, the satin piping, and the soft hand feel intact.
How to wash the set
Follow these steps each time to protect the fabric and the flat satin piping.
- Hand wash in cool water: Use a mild detergent. Do not wring or twist the fabric. Gently swish the top and boxer in the water, then rinse thoroughly.
- Press out excess water: Lay the set flat on a clean towel, roll the towel up, and press gently. This removes moisture without stretching the knit.
- Air dry flat: Shape the pieces and let them dry away from direct heat or sunlight. Never use a dryer, even on low.
Product details that affect sizing and care
- Short Sleeve Top & Boxer Set: Body: 50% Cotton, 50% Modal. Pre-shrunk, breathable, wrinkle-free, pill-resistant. The pre-shrunk fabric means the set won't shrink much after washing, so you can order your usual size. The modal gives it a soft drape that holds its shape if you hand wash correctly.
Short Sleeve Top & Boxer Set - Short Sleeve Top & Boxer Set: Hand wash only. Do not dry in the dryer. Machine washing or drying can damage the satin piping and cause pilling despite the pill-resistant claim. This is the single most important care rule for this set.
- Short Sleeve Top & Boxer Set: Relaxed fit button-down top. Comfortable mid-thigh boxer short with a soft, stay-in-place waistband. The relaxed fit means the top has some ease; if you prefer a closer fit, you might size down. The stay-in-place waistband keeps the boxer from shifting during sleep or lounging.
What the evidence doesn't settle about sizing
The supplied details confirm the top is relaxed fit and the boxer has a stay-in-place waistband, but they don't include a size chart or exact garment measurements. If you are between sizes, consider whether you prefer a looser or more fitted look in a relaxed-cut top. The available sizes run from XS to XXL in some colors (Mid Mod Floral Sabbia) and M to XXL in others (Heart Strings), so check the color-specific size availability before you order.
When to replace or refresh
The cotton-modal blend is durable, but hand washing is the main way to extend its life. If the satin piping starts to fray or the waistband loses its grip, it's time to replace the set. No amount of care can fix worn elastic. The set is designed for lounging and sleep, not high-heat or high-friction use, so treat it as a comfortable at-home piece.
