No way in hell are the sizes the same now.
The other week I pulled a dress, and a pencil skirt (out of the attic,) that I used to wear circa 1989-1991 when I first met DH - it was a size 12. DD (current size 8) tried to put them on, and couldn't get the skirt past her hips. She got the dress half on then gave up as she was worried about splitting it. It wouldn't go over her back and shoulders properly. As I said she is a current size 8! This dress - and skirt (from around 35 years ago,) were a size 12!!! Yet DD couldn't get them on!
MAN I was slim then, and I didn't know it. I found an old diary where I used to log my weight and vital statistics - (the diary was from 1988 when I was around 20.) I was 8 stone 3, and 34-22-34. I HAD A 22 INCH WAIST!
Soooo tiny, yet I thought I was 'curvy.' Didn't realise I was so slim. Didn't help that I had a boyfriend at the time (only lasted 2 months!) who put his arm round my waist in the cinema and said 'you've got a roll of fat there!' With a 22 inch waist I fucking doubt it! I was so angry and upset that I stormed out of the cinema, and dumped him later that night.
But yeah, the sizes are all to cock these days. The post further back in the thread (featuring pics of Marylin Monroe and Holly Willoughby) proves that. Both women are gorgeous, but no way is Marylin a size 16, and Holly a size 10. As I said, all to cock!
Many female celebrities do actually flat out lie about their dress size. Some claim to be a size 8 - or a 6, and I think 'nah mate,' The actress Nicola Coughlan from Derry Girls and Bridgerton (pictured here,) claims she is a size 10, and I'm like nope! Even in today's sizings she is a 14 minimum. (At times a 16 I reckon.) She's cute and pretty, but I don't know why she - and other curvy actresses have to lie about their dress size.
