she wears hoodies over it when we walk. Sometimes I have to reach my finger down in there, but it seems to work ok. It's not bulky at all so clothes do fit easily over it..I usually buy her clothes slightly bigger since I want to have extra room in case we need to put a harness underneath. the only funny thing is that it's like a half inch or so too big so if she pulls opposite of me, it will slide right off her. What size is Chloe now? Miya is about 13 or 13.5 inches in girth and the small is slightly too big, but the XS is too small.
