How weird/worrying is it for a babysitter to borrow clothing without asking?

Hello r/askparents! My wife in I have been twisted up in knots over this for the last few hours and I decided to see what a bunch of strangers on the internet thought. We have a young lady come watch our six month old a couple times a week for a few hours at a time. My wife and I are in our upper twenties. Today, I got home a little early and forgot to text the sitter to tell her I was on my way. I opened the apartment door and she came walking out of our bedroom. I found this a bit odd, but that bathroom is cleaner so I didn't think much of it. Then, I noticed she was wearing one of my wife's old oversized sweatshirts. I also didn't question this thinking my wife must have told her she could borrow it. She got my daughter up from her nap and told me how the last few hours went. Then, she said she needed to change back into her clothes before she left. I asked if she'd been cold and (and here's where I wish I could remember exactly what she said) she said something about my wife telling her to be careful about the necklaces she wore around the baby and that she had worn a scratchy shirt. I really don't remember if she said my wife had given permission or told her to take it. Anyway, my wife got home an hour later and found the sitter's necklace in her closet. I said she must have forgotten it in there when she changed and that started us down this rabbit hole. My wife has never told her she could borrow any clothing. We really don't even care that much that she did. We find it odd she didn't ask, but the part bothering us is that she seems to have misrepresented the situation. I would think she would have explained as soon as I got home. Although, it's also possible she was thrown off by my early arrival (she is young and timid and I have only interacted with her a few times. I am a bigger guy.) I called her to ask about it and she said she hadn't meant to mislead me and she apologized for not asking permission to wear the shirt. She came well recommended from a friend and she has seemed nothing but wonderful for the last few months. Our baby seems to love her. We are trying to figure out if we're making a mountain out of a mole hill. We would hate to lose such a good sitter and can't afford to go without, but if this is a legitimate concern and we can't trust her, obviously that is higher priority. So, if you've made it this far, how weird is it for her to have gone into my wife's closet and grabbed a sweatshirt without permission, then not explained until questioned? via /r/Parenting http://ift.tt/2eHM2Ck
