It depends really. The outers from Jupiter onwards are retrograde for half the year, so I think they are either barely felt, or only seen from a collective level. Unless they are retrograding back and forth over a sensitive spot in your chart!
I have noticed Venus retrograde in particular is bad for makeovers, haircuts, beauty treatments, even buying decor and soft furnishings.
I've lost count the amount of disastrous hair and beauty treatments I've had specifically during Venus retrogrades, with the end of the story always being, "I cried on the way home!". The worst was a tattoo, which got ballsed up
I got it redone after Venus stationed direct, so I managed to salvage it!
Also, decor and furnishings. I remember buying what I thought was a sleek classy grey duvet cover and pillow set during a Venus retrograde.
Once Venus went direct, I realised that the shade of grey was not so classy, but more like a shade of grey that was so depressing, it made my room look like a hospital! I gave it away in the end.
So I make it my strict rule now, no clothes or decor purchases, or hair and beauty treatments, until Venus officially leaves shadow. If I'm tempted, I will leave it in the checkout basket icon, and then come back to it after the retrograde.
10 out of 10 times, the checkout basket gets emptied!
