Do you know anything about cosmetics? I was thinking of going to the store and buying some makeup.
A thing or two.  What are you looking to get?   Maybe something for your face or hair?
Well I think I need some mascara and possibly some foundation. I really don't know anything about cosmetics.
You can usually get Mascara three ways liquid, cake, or cream.  I prefer liquid.  What do you think you might get?
Hmm I think liquid mascara would be a good idea. Do you usually use a little brush to apply it?
Yes, Normally that is how it works.  They come with a little brush or a Rod.  One you decide on one then you need to decide color too and various other attributes.  I normally get Black and lengthening.  But you could get curing.  What are you looking to get as an end result?
Oh I see. I just want to look pretty for my date tonight. I saw some fashion magazines with people wearing makeup. I will take your suggestions. What matching lipstick should I get?
I don't use lipstick so no idea.  I know there are a lot to pick from.  Maybe a balm that way it hydrates as well.  Or ar eyou wanting to find a color?
