Lovely brandname dresses for a night out/ party

I have 3 dresses for sale.
The first one (black and white) is a SPORTMAX (maxmara) dress. I'm selling it for $100.

I'm selling the second one for $20 (red & black)

The third one is a Blackberry dress. $120 OBO

If you buy 2 dresses together I will give you a 10% discount. If you buys 3 dresses I will sell it for $270.
I've only worn the 1st dress once, and the other two a few times. They are still in very good condition.
All are equivalent to US sizes 0/S.
