    The below edition of Self Checkout was created in partnership with Spanx.

    Friends! The way I see it, getting dressed for work during the spring and summer is like riding a bike. You may think you’ve absolutely forgotten how to do it—especially on those first few warm weather days that sort of pop up out of nowhere—but with a couple of rides (or days of getting dressed in a row) under your belt, it comes back with ease.

    My trick? First, it starts with revisiting photos of myself from years prior during this exact time period. What did I post on IG? Which outfits did I love and should therefore repeat? Which ones need a little update or tweak? I am the blueprint, after all. Next, we study the throughlines— what were the wardrobe workhorses that I can turn to time and time again? Once I’ve gotten that in order, then I shop, should I need anything else.

    This week’s send will focus on a few of those workhorses, in collaboration with Spanx’s WellSuited collection, and other pieces I’m absolutely loving from the brand.

    You guys know me, I’m a suiting girl through and through. It’s where I feel most put together. Spanx’s WellSuited collection has a host of pieces that can be dressed up or down and are fab to travel with because they don’t really wrinkle. Let’s get started!

    THE VEST

    Vest outfits were super trendy last summer, but they don’t really ever go out of style. If I’m feeling super formal, I’ll pair my vest with trousers and maybe even a blazer (you never know when the AC will be on full blast). Otherwise, a pair of wide-leg jeans or Bermuda shorts make for a good match.

    PENCIL SKIRT

    A pencil skirt will be an ambitious update for me. As you guys know, I can’t stop thinking (writing) about the skirt suit trend, but I’ll admit, I’m still working through how it would fit into my day-to-day life since my office is more casual. If I were a lawyer or proper corporate baddie, though, I’d 100 percent go full skirt suit, plus a personality pump.

    BLACK BLAZER

    If you don’t own a black blazer…you probably should. I’m rarely prescriptive when it comes to my fashion recs, but a black blazer will always hold you down. This Spanx one is especially great because of the all-season fabric and four-way stretch. I’d size up for a more slouchy look, then be prepared to wear it with everything you own. Another tip: Stash one at your office to replace your desk sweater.
