I mostly have to repeat order 53,35,7,31,14,45, for summer cga 37 and 8 are popular also 18 which comes in the start kit.
I think i nearly have them all now and most are used at some point or other and if you keep them well away from light and cool they keep really well. I have mine in a metal tool box from b an q which looks just like a professional beauty box bugt it was a lot lot cheaper.
Remember they do a buy 5 and get 1 free offer which can also include a pot of the super clear which is good for french especially in the summer to prevent yellowing.
They are all lovely even the ones that you think are yucky are nice on.
Dont forget they mix really well to which i do if i get low in a few pots.
Or you can put one over the other for a subtle change.
The colour palette thing they do is really handy its a bit of an expense but worth it as its more true to life than the chart and the client can see what the colours look like with her skin tone.
