H&M sleeveless, curved hem tunic with key hole neckline

H&M sleeveless, curved hem tunic with a peek-a-boo keyhole neckline, and button closure in the back. Fabric is gooey and slightly sheer. I never wore anything under it other than a bra, so it’s not totally sheer. Excellent, pre-owned condition. It was long enough for me to wear with leggings, or it can be tucked in. Top of shoulder to bottom hem is about 31”. Smoke-free, Labrador-friendly home.
