Vintage 1960s 1970s CARLYE Floral Embroidered Cutwork Green Linen Dress SMALL?

Very pretty, light green dress with white + ivory embroidery + cutwork. Lined. Short sleeve. Zips up back with hook + eye closure at back of neck. Mock turtle neck is creased, as shown in pic. I believe once it is being worn and the hook + eye closure is latched, that it should increase, but, it may require some finessing. Please view all pictures for size measurement, as there is no size label. I believe it may fit like a small. No material label. Feels like a linen outer.
