St. Patrick’s Day is the perfect excuse to lean into all things green, comfy and festive – and Aerie is basically MADE for it. Whether you’re heading out for a low-key hang with friends, grabbing a shamrock latte or keeping things chill at home, this year is all about St. Patrick’s outfits that feel good, show off your style and let you celebrate without sacrificing comfort.
Cozy and Cool Athleisure for the Win
The key to nailing the cozy-chic St. Patrick’s Day look is a cute oversized green hoodie or sweatshirt. This is the centerpiece of your outfit, providing both festive color and maximum comfort. Look for shades of emerald, forest, or an on-theme clover green—the brighter the color, the better! Pair your oversized top with comfortable bottoms that are perfect for a day of activities, whether you’re relaxing at home or heading out for a casual celebration:
- Leggings: High-waisted black or dark gray leggings create an ultra-comfy base that pairs effortlessly with any green top—from a graphic tee to a cozy oversized sweater. Consider a brushed or fleece-lined option if the weather is still chilly.
- Joggers: For a slightly more relaxed, street-style vibe, choose soft joggers. Go for neutral bottoms like classic black, deep charcoal, or even a cool heather gray so your festive green really pops!. Perfect for a casual parade-watching or a home gathering.
- Baggy Sweatpants: Embrace the trendiest way to get comfy. Oversized, baggy sweatpants in neutral tones like oat, stone, or deep forest green (if you want to subtly lean into the theme) create a perfectly cozy and on-trend St. Patrick’s Day outfit. Pair them with a fitted crop top or a tucked-in graphic tee and layer with an open puffer vest for added texture and style.
Don’t forget the fun accessories! A simple shamrock baseball cap, green scrunchie, or delicate gold jewelry can add subtle attitude. A minimalist green crossbody bag is also a great option for carrying your essentials.

Casual Dresses for Easy Green Vibes
If you’re glamming it up but still want Aerie-level comfort for your St. Patrick’s Day look, a simple green dress is the move. It’s the perfect one-and-done outfit that keeps the good vibes flowing all day long. Look for a super soft, incredibly flowy mini dress—think lightweight cotton blends or cozy knits—in a shade of green that speaks to you. A delicate sage or a rich, jewel-toned emerald green offers the perfect nod to the holiday without feeling like a costume.
The beauty of a casual dress is in its versatility and comfort. You can easily rock it for low-key gathering, a coffee run, or a comfortable day on campus.
- Styling Tip: For peak coziness and to transition the look for cooler weather, layer it up! Throw on your favorite oversized cardigan or a comfy fleece crewneck sweatshirt right over the dress. If you opt for a crewneck, let the hem of the dress peek out underneath for a trendy, layered effect.

Add Pops of Color
For those who love to experiment with color, why not mix it up? While green is obviously the star of the show, add pops of other bright colors to make your outfit stand out. Pair a green blouse with a yellow skirt or some cute pink accessories for a playful twist. You’ll also be setting trends with your bold color choices.
If you’re aiming for a more understated outfit, start with a soft, romantic piece like a lace top in a sage or mint green. Pair this delicate piece with a staple like your favorite dark-wash or perfectly-distressed blue jeans for a grounded, “I woke up like this” vibe. The key to elevating this ensemble is in the details and the accessories. Add a little gold shimmer with thoughtfully chosen gold jewelry. Think simple yet impactful pieces like classic gold hoop earrings and delicate layered necklaces.

Celebrate in Style
This St. Patrick’s Day, have fun and celebrate in style with Aerie! Whether you’re going all-out with a green dress, keeping it comfy with athleisure or letting your accessories do the talking, there’s no wrong way to celebrate.
