Looks fantastic doesn't it? Brings back the bad memories of 1977 when DM thought I'd look great (age 15) in something similar.
Put it on, told her NO!! Yes I may have had the body but no way did I want to wear that.
I have not the slightest idea what she was thinking at all - she normally presented me with purple clothes - and she was a teacher too.
I'd sew a cross-tit, meet in the middle zip, if I lived in some parallel universe where I might consider wearing that thing.
