To add to the reply that you can't put free postage, then ask for postage in the ad (a buyer will demand free postage and there's nothing you can do about it. If you then charge postage, you can be guaranteed to get a negative), you also need to ask yourself, are you willing to let these go for 99c? There is a reasonable chance that you will only get one bidder who will win them for 99c. I lost out big time when I used to list the start price at 99c because everything was selling with only one bid. I would suggest that you have your start price at the minimum amount you are prepared to accept for them.
I would also add measurements. Saying they are size 6 really means nothing these days because every brand seems to have slightly different measurements. Measure inside and outside leg and also the waist, in cm. For the boots, I would measure the sole length and add that. I have seen too many people get negative feedback because the garment didn't fit due to differences in sizing. Try and put basic measurements in the title if there is room because people often don't read the description. They look at the title and the photos.
There have been a few incidences of late where clothes sellers have been accused of sending dirty or ripped clothing. I would suggest taking a LOT more photos of every square inch of each item, even the soles of the boots and the insides as best you can. You don't need to have all those photos on the listing, but have them available should someone come back at you and say there was something wrong. There are too many eBay shoplifters who open cases saying there is something wrong so they can get a refund. Also, if you do get bidders, check their feedback left for others and see if they leave negatives for other sellers and also check whether they regularly get refunds for either item not arrived, or item not as described. If they have, cancel their bid....otherwise you could easily be their next victim.
