I know I promised another Clash of the Polishes, and I will post that up tomorrow, but since I wore Astor 321 yesterday I did this comparison first. I hope you won't mind :)
So the difference between them seems very obvious, but in real life it's much less noticeable. My camera sort of picked up strong orange-rusty tones from In Stitches, but you can't exactly see that so much unless you hold your hand up right in front of your face.
Final verdict: They are not dupes, although the difference is not as obvious in real life as in the photos.
See you tomorrow for OPI - Road House Blues vs essie - No More Film!
