Okay.
I hope this works, but if it doesn't just tell me and I'll see if I can fix it.
Here are the outfit files, including instructions for setting them up for anyone that has trouble with plugins like I did when I started twiddling with them.
Full credit to aacewin for the summer dress, and to Rezzabae for his awesome hot pants (which are probably pretty well my favourite clothing item so far)
As for combining clothes, all I did was take the _plugin file from Rezzabae's REZ_Clothset and replace the file location of the items in it to the articles of clothing I wanted to use. It took a little playing with but ultimately it's fairly straight forward
