Vibrant Racer Back Tank !!!
Size: X-Small, Color: Hot Pink, Size: X-Small, Color: Hot Pink
I purchased this Danysu V Neck Racer Back Tank Top for Women Padded Ribbed Long Tank Fitted Basic Cami Tops to wear under my off-shoulder top for an upcoming 80’s dance party, and it works perfectly for what I needed! The bright pink color really pops and adds the perfect retro accent to my outfit. I intentionally ordered the XS because I did not want it to fit loose under my top, and it definitely gives a snug, fitted look. The ribbed material is soft and stretchy, and the built-in padding is a nice bonus. I would recommend sizing up if you plan to wear it alone or if you are curvier, as the XS runs very tight. However, for layering under another top as I did, it worked out exactly the way I wanted. Super cute, flattering, and great for layering or workouts!

My new Favourite Summer Tank Top - padded cup (no shelf bra!)
Size: X-Small, Color: Color Block Black, Size: X-Small, Color: Color Block Black
Cutest tank top, my new summer go-to. I was looking and searching high and low for a tank top which had padded cups without the shelf bra. Shelf bras are so uncomfortable with their elastic bands and are even worse in the summer, sweaty sun. I wanted something breathable, movable, and with just a bit of padding to cover the nipples and add the slightest big of shape. If you are large breasted these built in cups might not be the best for you, but as a smaller breasted lady these are perfect. The cups are not over the top bulky, but also they are not meant to really add "support" (for those who are looking for support this wouldn't be the tank for you. Think lightly padded!) The material is super soft and the length comes down to the hips. The tank doesn't ride up, so you're not always having to pull them down and adjust, and so you could wear them for both workouts or for casual summer evenings. I bought size XS and I am 5'1, 97 lbs. I was wondering if I should go to a size S because it wasn't clear by some of the reviews, but I'm glad I bought the XS because the shoulder strap is also the perfect length (not too baggy but also not super tight). Read the sizing chart before you buy - they are true to the size indicated on the sizing chart. Some have said theirs didn't come with padding, or the stitching was poor, but the ones I've received are totally fine. This tank is just plain-old comfortable any way you look at it. I'll be buying more colours!

Great workout tank
Size: Small, Color: Cocoa
Great workout tank with built-in padding. Fits true to size, is comfortable and soft that hugs your form. Only reason I’m giving 4 stars is because the pads do get shifted around during washes, which is typical but frustrating. I air dry and haven’t had any issues with shrinking either.

Cute but NOT supportive
Size: X-Large, Color: Floral Pink Rose, Size: X-Large, Color: Floral Pink Rose
These are NOT “workout” tanks offering support. They have a removable cup sewn into the front of the shirt, similar to a bathing suit. If you have small (or gloriously high) boobs and want a shirt to hide your nipples, this is great. If you want something to actually give support, this is NOT it. There is no band to provide support. So if you have large or low breasts, don’t even try. You’ll have to wear a bra with it unless you want your boobs hanging below the sewn in cups. That being said, the material is great. It’s nice and thick with lots of stretch. The cut is also adorable. And I LOVE all the colors. I wish it just had a supportive band!

Comfy & cute! But low support
Size: X-Large, Color: Ocean Depths
This tank is super comfortable and I LOVE the color. The built-in bra is a little weird; I thought it was sewn in backwards but apparently not. It has low/medium support, bigger chested folks may not like this. Im a 36D and its right on the line for support where I can't decide about wearing this in public. I sized up and am glad I did; it fits well! Im 5'7" and 165lbs for reference.
