Cami and tunic sweater set

Lovely Sud Cami and Tunic sweater set purchased in Paris No tags but never worn Soft sheer cap-sleeved T says L but is probably closer to a USA M. No fabric content seen but appears to be a cottom / modal feel. Longer tunic sweater is. M. No fabric content but feels like a cotton / linen blend. Sweater can be tightened / cinched at waist for a closer fit. Would look great with white denim pants.
