To fully take advantage of the 70s revival, snatch up something crochet like this Urban Outfitters dress on sale for $39.99, a folksy embroidered tunic (Forever 21 $22.80), and a glorious pair of flared jeans (Old Navy $36.94). This trend has been around the last few seasons and looks like it will be on an upswing through next year. So you may already have long chains, furry vests, and platform shoes at your disposal for boho fun.
Hemlines are dropping. Trade in your minis for a knee length or slightly longer skirt in a fall palette. I'm loving this plain teal skirt from Mod Cloth ($29.99). (Yes, I do think of teal as a fall color.)
Hemlines may be going down, but crop tops are making a comeback. I may be in the minority, but a crop sweater (ASOS $20.69) would be fantastic for fall's layering. So let's find something to layer under. I'm fond of this 3/4 sleeve tee (on clearance for $19.95 at Anthropologie) as the collar will add extra fun to an outfit but can be covered without bulk as well. A light, lacy cami (ASOS $22.41) will do little to keep you warm, but it will give a whiff of spring either peeking out from under a sweater or worn over a heavy dress.
For a splurge, either go with a great jacket or a great shoe. This short sleeved, pink lined kimono sleeve jacket (ASOS $86.20) would add a casual feminine touch to anything you wear. Speaking of casual femininity, these leather ribbon-trimmed sneakers (Betsey Johnson's "Drrew" at Nordstrom $89.95) are perfectly cute for dashing to class.
Unfortunately, getting both will break the bank. Which do you choose?
