that's a damn shame they don't list the sources for the objects they have in that lot
The chairs are from
mango sims from Set Cannelle on page 3 of dining rooms
I'm positive the suitcases are from mango sims as well (coz I had them myself at one point) but I can't for life of me find them on there now
for the handbags you could look on
Black Pearl Sims - quite a few of their creators are into clutter, you'll also find shoes, bottles and various other clutter here
There's this luggage set
here by BeosBoxBoy although they don't have the LV pattern - you could always put in a request for someone to recolour them. As part of the Petra set, BBB also made shoes and shoe boxes, you'll find those on all4sims.de too
edit: yes, the suitcases are on Mango Sims, and they are the ones shown in the pictures of that LV shop. They are in Set PML which is on Page 3 of the Others section
