That annoying thing

I love shopping -or more specifically love clothes- so as you can imagine, I have gone on many shopping trips in my time. You know how annoying it is when you go shopping because you desperately need something (like a top to go with your new wetlook leggings), but you cant find anything? Well I've noticed that the only time you literally cannot find anything, is when you're desperate. For example, when we went shopping for a dress for my sisters party and couldn't find anything, but the party was just a week away. Or when I really needed an outfit for a school competition but we didn't spot a thing. What is the reverse of this? When you're going shopping 'just to have a look' and you end up coming home with practically the whole petite section of Topshop (that has happened many a time), including things that you really don't need. Whats your opinion on my theory? While I'm on the subject of clothes... I was on a certain online shopping website (Topshop, as usual) and saw that the coat section is full to the brim with boyfriend style coats. I'm pretty sure this will be the 'in' thing for the winter. Unfortunately, I doubt they will do much to compliment my 5'2 and 1/2 frame. Another coat that I've just become familiar with is the 'coatigan' which is a coat/cardigan, which- if I'm brutally honest- I am not too fond of.
