Dilema of a Shopaholic

So a few weeks ago my lovely mommy<3 gave me money to go fall wardrobe shopping. 

(I must have been looking that depressed and sad because she never encourages my addictions.)

And I have been so busy with acclimating to school & work that I have not....I repeat...HAVE NOT...gone shopping.

This is a dilemma because I have my summer clothes and its been chilly on and off...I haven't the right things to wear...etc. So I HAVE to go this weekend and go H.A.M.

Considering its a month well into the fall and about 2 well in fall fashion, I'm debating on what to buy.

If I buy a bunch of stuff just for fall, I might be a bit too late because the spring things start coming out quite soon. 

So I'm thinking of buying some things that can easily transition into spring fashion (like color schemes, possible styles that are timeless, etc.) 

Considering I have a budget for once (trying to just use the money I received) I think it is safer to just make a list of what I need (& by need I mean want that is in season.)

The making list part is a piece of cake! The narrowing it down to fit my budget is the problem...

eek! Help me!

So I need assistance as to what is a MUST buy for the fall and what are the MUST haves in every girls closet that can be for any season!
