Awesome advice ladies! I just have one little suggestion - see if you can take a GOOD friend who has some fashion sense and good taste with you, and get an honest opinion when you're trying stuff on. I find that generally the sales ladies try to tell you what they think you want to hear, in order to make a sale. (not all of them - I've come across one or two who will tell the truth and make really good suggestions. But generally - they'll tell you it looks lovely, if they think you want to hear that! )
And I don't know about your DH, but mine isn't so good at objective opinions on clothes, either. More like "yes it's lovely, it's on sale, please buy it so we can go home!" You need a mother, a sister, or a best friend who is good at picking out clothing, will tell you the truth about how it looks on you, and can maybe get you to try some new/different things by throwing all kinds of stuff in the changeroom while you're in there.
All the best!
