RNA-N Cami Dress M Cotton Red There's a slit about 30cm long in the back. Width (laid flat): 52cm Shoulder straps can be adjusted to be about 5cm longer, but from the shoulder down as pictured is about 123cm. It's a sturdy cotton rib knit, so it's not see-through even without a lining. There's some loose thread visible under the arm. I don't think it's been worn very much. This item belongs to a family member. Thank you.
