Here we have a fan fav Linsey Dawn McKenzie - and some perspective.
This is an interesting one, because I know of this woman. I can remember a lot about her in the UK newspapers in the mid-90s. They promoted her as 36HH at the time - which was probably the size she was given using the +4 technique at Marks and Spencer. A 36HH sounds big, and I suppose it is in relative terms, but she’s not a 36HH (and, as I understand it, she had a reduction and then went back and got implants), so things will be different now.
In this photo, she’s about 5’2”, based on the tape measurement and fairly broad shouldered - but still slim (I am super-jealous of jus how slim!). So, I’m thinking she’s in the 30-32 back region, with a J-K cup. I’m thinking 32J/JJ - she has very similar projection and bodyshape to someone I know, and she’s a slightly bigger 32K, so I reckon 32JJ is probably about right (depending on the bra).
