I purchased this on Mercari a few years ago. The waist is a bit loose, so I think it would be wearable for those who are starting to show during pregnancy. I wore it after giving birth, and I don't remember if I bought it specifically as maternity wear. It comes with a detachable collar. You can wear it without a petticoat, but there's a possibility that the straps of your underwear or camisole might show through. Please check photo 3, where I've put my hand in to show the see-through area. It has a tulle overlay, and the design is simple yet very cute! Top Length: approx. 53 cm (including tulle) Shoulder width: approx. 35 cm Armpit to armpit: approx. 42 cm Pants Length: approx. 94 cm Waist: approx. 34 cm Inseam: approx. 61 cm 15 cm below the waist: approx. 45 cm (This is around the fullest part of the hip area) Measurements are taken flat. Please feel free to ask any questions! ☆ Please only purchase if you understand that this is a used item. I will ship it as compactly as possible. I'm sorry, but I cannot offer discounts. (´._.｀)
