If you could only have 4 bags - which ones would you choose?

There is a similar thread but one is only limited to three bags.
In September 2013, I wrote these:

1. BV Nero Cabat. (This hasn't changed)
2. BV large Veneta in a good blue. (I'd now want a good neutral like tan)
3. BV knot or iron Bag in purple. (I'm torn, I might like red)

Since I get to add a fourth,
4: BV cervo hobo in blue

A year later (well almost) and I'd change 2 and 4. I'm more clear on 3. So my list is:

1. BV Nero Cabat
2. BV Cervo Loop Hobo (I have it in new light grey and it's amazing)
3. BV Knot
4. BV Pillow
 
1.Bottega Veneta knot
2.Chanel 225 reissue
3.Balenciaga City
4.Hermes 35cm Birkin

I'm halfway with the list owning 2 and 3, would love 1 soon! and 4, well.. i don't think i'd ever get there, but I can dream.
