Polkadot Pastiche

Hi Everyone!

B and I are headed to England the last two weeks of August! We'll be spending most of the trip visiting his family outside Manchester, and 2-3 days in London on our own for a little sight seeing. I'm really excited, because this will be my first trip to England and my first time visiting a place outside the US. Of course my first thoughts were on what to wear. ;)

I know the weather can differ quite a lot between northern and southern England, and that the weather can vary a lot even during the course of one day. Also, Londoners wear a lot of black (is that true?). I don't own anything black. :( If anyone can give me any more guidance, that would be great. I live in Texas, so "hot" weather to me means anything above 90. 

I used Pinterest to put together a potential travel capsule, but I'd love some feedback from YLFers who are in England or have visited during the summer. 

My goal is to take 3 bottoms, 3 shirts, 3 "toppers" (layering pieces), 1 dress, 3 pairs of comfortable walking shoes, my trenchcoat, umbrella and 1 handbag, plus a few small accessories. That makes 7 outfits that I plan to wear twice each (we'll be able to do laundry while there). The hitch is I do not want to buy anything new just to take to England, especially things that I would never wear here in Texas. The trip is going to be quite expensive, and we just don't have much to spare for clothes. The items below are all things I already own (or close approximations). 

So, does this capsule seem okay? Again, most of the things we'll be doing are really casual--visiting family and touring museums and hanging out at the pub. We won't be attending fancy dinner parties or theaters or really nice meals out (maybe next time). :)

P.S. If any YLF peeps will be around London at the end of August and have time, I would love to meet up for lunch and a little browsing/shopping. :)

Here's my Travel Pinterest board if you're interested in seeing the actual items I have.

Thanks again! :D
