21 Spring Essentials in Flash Sales at Madewell, Banana Republic, and Shopbop

[I was wearing ankle boots and a sweater to work last week, but this morning I overheated with the same outfit. It's time to get serious about spring essentials, and I'm taking advantage of big sales at Madewell, Banana Republic, and Shopbop to fill holes in my wardrobe.

Office-ready tank tops, spring shoes, and versatile button-down shirts are a few seasonal items I need. What I'm looking for are anti-trend staples that I can use again and again throughout the season. I'm not building a capsule wardrobe, just one that works regardless of the weather.

Luckily for my wallet (and yours), three of my favorite retailers I frequent for quality basics are having sales that are too good to pass up. You need to know the details of each sale, and keep scrolling to shop all of the spring essentials I've found.

Use the promotional code SPRING30 to save an additional 30% off over 1,400 items currently on sale at Madewell. That means up to 70% off select items, through April 24.

Just when you thought Banana Republic's sale was great, it gets even better. From now until April 24, Banana Republic is offering an additional 20% off sale items.

Shopbop's sale section is really great right now. Thousands of items are up to 70 percent off, and no promo code is needed. However, this sale ends April 25.
