Linen Blend Blue and White Striped Boat Neck Top Women’s Size M

This short sleeve top is in excellent condition. Soft linen/cotton blend. Blue and white stripes. Brand and size label is missing. Measures 18” across chest when pulled straight but top is intended to fit loosely. It may actually be a maternity top but is missing tags. I tried it on and was still not sure. It has a bit of an a-line shape and measures 21.5” across bottom. 24” shoulder to hem.
