50s White Floral Print Dress by Henry Lee
No fabric content tag, so I cannot say for sure what the material is but has a crepe feel with smooth lining. Thin and non-stretch. Metal zipper in back of dress.
size 10 fits like modern S. Measurements of dress: 17" across underarm to underarm, 12. 5" across the waist, 19" across at the hips. 34" around bust, 25" around waist, 38" around hips, 15. 5" bodice, 40" long - Model is 5'1" XS 31/24/34. Allow room for comfort, movement, breathing.
Flaws: Underarms appear more gray than rest of dress. Obvious fold line above current hem and some stitch marks higher above that - someone must have wanted this quite short!

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