She looks so regal in this violet sized Medium. I had also purchased a duplicate in SMALL (just in case as I didn't know how it'd fit) and there is NO WAY she can fit it. After putting her front legs through, you can't even pull it back to reach the back legs to insert those in.
The back legs though don't ride very low and it's quite loose so you get a slight "baggy" look when she's positioned a certain way. The outfit actually looks much better in person and on her.
It's almost like having a very classy set of robes on... I can almost see her smoking a cigar or pipe with it on.
(We're a non-smoking household, I promise).
