Hi, welcome to YT
That's so great you get to travel and take your baby with you, England is on the top of my list of places I still want to travel to
I have some "hoodies" for Alice and she seems sooo comfy in them. It's thicker than a tee-shirt and there's no buttons, hooks or velcro so thats why I think she likes them. I picked them up for about $7 each at a local small pet store (I'd imagine it's a little harder to find warm clothes in FL lol). I haven't shopped online for any doggie clothes yet, so I can't direct you there, but I know that there are a few YT members that sell clothes. Check in the "products and reviews" category and also the section on threads where those members selling items can post their links. You'll have so many choices your head will spin LOL
