A soft, non clingy top that fits perfectly!
Color: Print 02, Size: X-Large
This is such a versatile top . The sleeves are a perfect length. The material is high quality and the colors are so pretty. It launders well with no wrinkles. I will definitely be ordering more tops from WIHOLL. Great top at a great price.

Nice quality casual shirt
Color: Print 02, Size: Large
I love this shirt! It was true to size, color and fit! I washed it in cold water and dried on permanent press. Put on a hanger immediately out of the dryer - no wrinkles! No shrinkage and no fade. Materials is light but is not see thru.

Very flattering
Color: Boho Print 03, Size: X-Large
Great shirts! I have a large bust, and they still look great! They're comfortable and don't cling, and they're machine wash and tumble dry low. This is my third one, and I may buy more.

Great feel and color
Size: Medium, Color: Ocean Depths, Size: Medium, Color: Ocean Depths
Absolutely love this tank top! The color is gorgeous and exactly like the pictures — super vibrant and flattering. The ribbed material feels soft but still has enough stretch to hug in all the right places. I also really like the built-in padding and racerback style because it makes it easy to wear without needing extra layers.
The only thing I would mention is that it runs a little small, especially if you want a more relaxed fit. I’d recommend sizing up if you’re between sizes. Other than that, it’s a great basic top that looks cute dressed up or casual!

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!
