Longsleeve Jersey cardigan with crochet back panel

Cute long sleeve jersey/T-shirt type cardigan Back panel completely sheer/crochet style Super cute over a white or gray tank and Jean shorts It’s a a dark slate gray that in some light can have a subtle deep lavender tone Gently worn / no rips stains etc. I removed the brand tag so it wouldn’t show through the back panel - don’t remember brand. Was purchased at a small boutique in Virginia - not expensive - just cute
