50s 60s Union Made Bellas Hess National Blue Linen Dress - paper tag is still intact so beyond my modeling it, may not have been worn.
Super flattering. Decorative belt buckle under bust and pleats at hem and back. Side metal zip. Half or 3/4 sleeves.
32" bust, 24" waist, 34" hips, 16" long to waist, 43" total length, 2" hem allowance - model is 5'1" XS. 14" shoulders, 15" sleeve. size 10 - approx modern XS/0
No material content tag but feels just like linen - fraying as linen does at inside seams.
Flaws: 1/8 inch faint discoloration on lower shoulder area, Speck of discoloration on back pleats. Very subtle fade directly at shoulder from hanging (not obvious enough to pick up in a photo).

This item is sold from an excellent, highly rated vintage boutique.
