Vintage 1970s Red Maxi Dress Butterfly wing sleeves attached Rose

Here for your consideration is a nice vintage 1970s Red Maxi dress. The brand is Strait Line and it is marked size 12 It is a polyester knit light weight fabric . I would estimate this at a modern medium based on the measurements. Here are the measurements with the dress flat and taken from one side. Arm pit to pit 16" waist is about 15.5" but has some elastic to stretch a pit more , length 54". This dress is clean and has no holes or stains.
