Is the office AC turned up a bit more than usual, or are we just starting to feel an imaginary chill from all this fall fashion talk? It always seems like right after you finally nail your warm weather 9-to-5 style, tanks, maxis and heeled sandals need to be subbed for more substantial pieces, and that transitional turnover can seem really overwhelming (navigating new trends is one thing, plotting how to layer them is another story). But it doesn鈥檛 have to be. Instead of reaching in the back of your closet and settling for last season鈥檚 same-old looks, here are five easy work wardrobe swaps you can make to stay stylish at the office now through fall 鈥 and all for under $100.

Ditch the Blazer for: a Sleeveless Blazer

ASOS Sleeveless Ponte Blazer ($69): You鈥檒l never think of the traditional blazer as the end-all-be-all work layer ever again once you slip on a sleeveless version. Similar to a tailored jacket, this garment streamlines any outfit, just in a very of-the-moment way. Use its exaggerated hemline to break up the proportions of your outfit when you鈥檙e wearing a maxi dress or long pants or to dress up a sweatshirt when you鈥檙e letting the cozy girl boss in you shine.

Ditch the Oxford Shirt for: a Shirt Dress

Zara Linen Shirtdress Belt ($50): What鈥檚 better than getting the same professional polish as an Oxford shirt in toss-on-and-go form? Wear your shirtdress with mules these last days of summer to give the look some easy edge. When things start getting breezy, throw a pair of trousers on underneath. Otherwise, a pair of colorful tights and knee-high boots should be your backups.

Ditch the聽Pencil Skirt for: an Envelope Skirt

Topshop Crepe Wrap Midi Skirt ($75): Thanks to the wrap detail that forms a subtle, asymmetrical hemline, your go-to office skirt just became a water cooler talking point. It鈥檚 the modern way to mix a classic, more conservative cut with sexy details 鈥 consider it a must-have if you鈥檙e a desk-to-date regular.

Ditch the Basic Work Pumps for: Minimalist Loafers

Urban Outfitters Ivy Loafer ($59): Not only will your feet thank you for this wardrobe swap, but minimalist loafers will be as effortless to pair with your work uniform as those basic work pumps. It gets even better: because of their masculine flare, these versatile shoes will give outfits you鈥檝e worn time and again a completely different feel (did you hear that, lazy girls?)

Ditch the Tailored Trousers for: Culottes

Nasty Gal Cool Lots Culottes ($58): Just like kimonos did last year, getaway-synonomous culottes have made a full transition into any-season wear. How can you not be intrigued by the thought of wearing these cropped trousers to work? They have an effortlessly chic feel, but are structured enough to go with your best power tops. If you鈥檝e learned to pull off sweats at the office, this is your next step.
