Parisian PetBarking Diva Dog T-Shirt, Large

I have been reading reviews and am having a hard time deciding between an xl and an xxl. I have a mini daschund. Length is 17, neck 12, chest 18.

Does this come in hot pink or coral

Which size would be recommended for a dog with a length of 10", a neck of 8-ish, and a 12.5" chest? Is one measurement more important another ?

My dog is a 26-28lb scottish terrier i ordered medium but it was way too small. according to the chart she will wear x-large. is that right?
