Black PolkaDot CoreSupport Underscrub
The CoreSupport you know — in the polkadot you asked for. And asked for. And kept asking for. Same zoned compression-style knit, same fitted supportive feel through the core, now in black with tonal textured dots. The dots read subtle at arm's length and unmistakable up close — visible texture that sits flat and low-profile under a scrub top.
Our most premium fabric — ever 🤍
This is the most premium fabric we've ever made an underscrub from. An upgraded four-way-stretch performance knit with a buttery-soft, sculpting hand-feel — the same premium performance fabric used by well-known activewear brands that retail for $100 and up. You're getting that quality at a fraction of the price. We'd rather you feel the difference than pay extra for someone else's logo.
Under the upgrade, it's the zoned-support CoreSupport fit you know: denser knit through the abdomen and lower back for a supportive, smoothing feel, lighter through the sleeves and shoulders so reaching and lifting never fight the fabric. A fitted base layer engineered for long healthcare shifts — not a medical compression garment, and we make no medical-grade compression claims.

Fit & sizing

Pairs with
Layer it under your scrub top — the tonal dots stay subtle and the crew neckline sits flat under a V-neck. If you want the same fit in a solid, the CoreSupport Performance Underscrub is the same garment in Walnut Brown, Navy Blue, and Baby Blue. See the full underscrub collection. Want the full polka set? The original White PolkaDot FlexForm is its sister piece.

If you hate attention and don’t want to make new friends don’t get this top. 1. The polka dots are not vinyl they’re fabric and slightly raised and the monochromatic look is stunning. 2. Mid report a nurse told me she liked my top, another one said we’d be good friend based on my top, it just makes you so approachable! Perfect for a comfy cutesy fit!
My absolute favorite underscrub I’ve ever bought! I get compliments on this top every time I wear it. The xs actually hugs my skin and fits great, which is hard to find as a petite girl. 10 stars if I could!!
I LOVE my ALA underscrub. It is so comfortable and it kept me warm all day. The material is stretchy so I didn’t feel like I was suffocating. I also wore it as a shirt and got so many compliments!! I HIGHLY recommend!!
LOVE LOVE LOVE! This top is actually perfect I’m obsessed with it! So many compliments every time I wear it!

Absolutely gorgeous underscrubs. Everyone complimented me when I wore them but the best part is how warm they keep me <3 can’t wait to get more and keep elevating all my scrub fits with these underscrubs
amazing
So cute!! I’ve gotten so many compliments! This one fits a little smaller than my other ALA underscrubs so size up one!!
I absolutely love this underscrub! The pattern is SO cute and adds a fun pop of personality while still looking professional enough for work. The quality is great, and it’s really comfortable and lightweight. I also love that I don’t get too hot wearing it throughout the day. Such a cute and practical addition to my work wardrobe — I’ll definitely be getting more!
comfortable compression, perfect sizing. my new favorite underscrub
Super cute and comfortable!
I typically wear a size large (often times it is too big) and your size large is a bit snug for me.
Nice shirt but ran extremely small. I sized up 1 but it was still way too tight and short. Unfortunately I had to return it.
Love it!
The material is horrible and not worth what you pay for.
The shirt is exactly as pictured. Very good quality, but runs extremely small. I am usually a size Large, ordered XL and it fits like a small.

So amazing! The fabric, the fit, the way it can be paired with all of my scrubs and look adorable!!! So happy I got this one to add to my growing collection of Ala under scrubs!!!
I love love love this underscrub! I have purchased from ALA since they first started and loved every top I have bought but this one tops all of them. It is the perfect way to upgrade your fit in black scrub jail while staying cute on comfy all day!! Highly recommend Ala and even more so the black on black polkadot!
Absolutely love this black on black polka dot underscrub! The fit is a perfect form fitting material and so flattering on anyone! The subtle black polka dots are such a cute detail and I have so many people asking where I got it from! Definitely a new work favorite!
This top looks so cute under all my scrubs. The polkadots are raised and add that extra texture look my outfit needs. These shirts hold up in the wash and don’t collect lint!
So cute highly recommend.
It's cute but they run very small. The XL fits like a medium. Also very short in length....these shirts are not made for long torso girlies
So cute!! I love the fit and feel so much! Loved it so so much I had to order another one for my friend!!! She loves her too so so much and now we get to be work twins!!!
Absolutely love this top! I can only wear black at work so this makes it a little more fun. The material is thick enough where you’ll be warm but won’t over heat. I just wish the top was a little longer, I have high rise scrub pants and it’s barely long enough to tuck in.
I love the pattern and the material is nice. It was much shorter than I was expecting but it will work under my scrubs.
Absolutely love this for my ER shifts, I’ve gotten so many compliments!!
So cute & Great quality!!! I’m obsessed!
Wish they made bigger sizes
Love it! - Super cute and comfortable!
