Well you look gorgeous in it Bijou. I love the colour and pattern.
I think for me, being just that ??10 years or so older than you I didn’t wear them when they were in fashion before. I am much more an 80s girl than a 90s girl, was so busy having the kids in the 90s I never picked up a fashion magazine and liked the leggings/long jumpers look for its ease and comfort.
I associate the spaghetti straps with the 00s when my girls were teenagers- Rebecca’s Year 13 ball dress in 2008 had them, but it was more full-skirted not a slip.
I do like to wear strapless bras with my maxi dresses as the wide straps on them sort of gape and show my bra straps, which I do not like. I get really annoyed with falling-down bra straps too! I am like Rachylou with very sloping shoulders. I agree that maybe we like to wear again what we liked in our 20s- if we can pull it off still, which you absolutely can!
I can do it with bright 80s colours which I never stopped liking
