WRONG WRONG WRONG.  This might appeal to grandma, which is ok if  you only want to sell to that 80 year old women but your pic says party,  your words say pooper...

We want to make this a little more fun and exciting. - Remember your gradeschool education?  Use the 5 W's: Who, what, where, when and WHY...

Who is your target - write your add pointed at this demographic and your best friend

What are you selling - be descriptive and  write your add as if you were describing it to your best friend

Where - could help to add where you came about the item again relationship building

When - if you have restrictions or special shipping guidelines, or delays...

Why are  you selling - this adds a personal touch and will help others relate to you

Heres a more personable example using your picture:

Cute and comfy white bra and panty set -  Ladies, are you tired of fixing your thong? (this relates to ALOT of women) Slip into comfort with this smooth finish, cotton bra and panty combo.  The bra is size 36c and features underwire support and is slightly padded.  The panties are medium, and feature the comfort of a full back, while still giving you the sexy bikini cut in the front. These are brand new with tags and come to you in a great box; Great for gift giving. (way more descriptive right?  And you've just opened your market by adding its giftable)  Please contact me if you have any questions in regards to shipping outside of the USA. Item will ship immediately after payment is received. (where and when covered) I bet you're wondering why I'm selling such a hot item...   The truth is, I liked them so much I bought one in every color and accidently got 2 in white. (why?  sound human enough?  Ever done this?  I know I have).

Much better right.  This same principal applys to EVERYTHING you sell from car parts to tea bags.  Some of the highest closed ebay auctions were not people bidding on the item so much as the story the seller told to reel them in.

Good luck and happy posting!
