I bought a large amount of dresses from a retired lady on Etsy.  I am going to list them.  My baby is old.  I am 69 years old.  So, I probably will not be getting any more fur babies.  The lady that I bought the dresses from no longer sews.  I really do not know if the material is polyester or cotton.  I think it is polyester. The material seems to be strong.   The items that I bought from her was well handcrafted.  She payed special attention in making sure that all her items were well constructed and could withstand a lot of wear.  The detail she payed attention to could be easily seen in the dress.  There is a ring that you can attach a leash to and walk your dog.  There is a metal anchor on the ring.  The dress is so cute and fancy.  The waist, with the velcro completely close is 13 inches.  The velcro is 2 inches.  So, if you need a little more room, you have some adjustment room.  The neck is 8 inches.  The velcro is 2.25.  So, there is some adjustment room in the neck, if you need it.   The dress is approximately 10 inches long.  Get your fur baby dolled up.  I am selling the dresses for a lot less then I bought them for.  If you have any questions, please ask.  Please check out my other listings.  Have a pleasant and blessed day.
