Wow, loads of replies, thanks!
Ok, here goes:
TapselteerieO- I do not like the first one, it doesn't look like it would comfortable fit an A4 folder/laptop combo- although the colour is what I want. Which rules out the other two, sorry. I am not keen on Peony and Moore bags either. Thanks for looking though.
Popbiscuit I had a look at the site, thanks. They do ship to the UK. The only one I sort of like is this one but it's a bit like a shopper and I'm not sure I want to pay that much for something I sort of like IYSWIM. Will keep an eye on the site though, thanks.
Gillybobs That one is the wrong shape for me I think- I need something a bit less slouchy. Thanks though.
MarineIguana Not keen on any of those, sorry! Straps are too long or too short and I really want tan I'm afraid...
strictlysauvignon Peony and Moore bags just don't do it for me I'm afraid. Appreciate you looking though.
ameliameerkat All those bags look lovely but all have too long a strap; I want a bag to sit just under my arm IYSWIM. However, I did think of getting the large retro satchel and shortening the strap, but they are out of stock 
netbook Got your message- Phew! Was panicking as the website no longer exists
Hence I am in this position. If you have any contact details for them, please PM me. I am after a smart bag. I like the shape of the per una one, but I want a deep tan colour. Also not sure about the pattern on it. Close though! Tk maxx ones not deep enough and Clarks one is a bit too casual, although it is growing on me...
moragbellingham No satchels I'm afraid
and not keen on the slouchy one. I want something a bit more boxy I think. Thanks though.
Thanks to all of you for looking. I think I am giving up hope now- my perfect bag does not exist
