Compared within this brand.
| Tropical Expression Flowy Nightshirt: Choose this if you want a loose, short-sleeve button-front nightshirt in a lightweight, flowy blend of 55 percent TENCEL modal and 45 percent organic cotton, with a camp collar, drop shoulders, side vents, and a knee-length cut in an all-over white tropical palm print on brown. It comes in Patterned Brown in sizes X-Small to X-Large and Dusky Pink in sizes X-Small to Large, though the fabric shows slight natural wrinkles in photos.[1,2,3] | Flowy Gauze Nightshirt: Choose this if you want a soft, relaxed cotton gauze nightshirt for summer sleeping or all-day lounging — reviewers with sensitive skin call it their most comfortable sleepwear, and the casual cut and quick-drying cotton make it a versatile beach or pool cover-up. Note the relaxed fit runs large, so straighter frames often size down while hip-heavy builds size up, and on taller frames (5 feet 8 inches and up) the hem can hit at the thigh like a tunic. Also know the fabric opacity varies between colors — some shades are see-through and others opaque — and the thicker-than-average weave may feel warm on the hottest nights.[4] | Vibrant Striped Seersucker Nightshirt: Choose this if you want a loose, boxy short nightshirt in breathable 100% organic cotton seersucker with a puckered texture and narrow vertical stripes. It buttons down the front with a pointed shirt collar, short loose sleeves, a slightly curved hem with mini side vents, and falls above mid-thigh. It comes in Patterned Blue and Patterned Orange colorways across X-SMALL to LARGE; listings show differing pocket descriptions (one chest pocket versus two), so check the variant photos if pockets matter to you.[5,6,7,8] |
