Delivery was just on the last day's of Delivery estimate,but within E.T.A just,So No complaints.Cotton is of Good Quality.Fit is Prerfect to 5% bigger. Very Good but Not perfect,but at Ordering would have taken V.Good AnyDay!!Only Slight thing(as NO Bleeding,NO Smudging or ANY probs with acctual writing,is that the Red/Black and T-Shirt Colour isn't as Bold/Bright as in picture.BUT! When i took pic's of T-Shirt on my Phone for this review,it again looked like Bolder/Brighter Colours by 10-15% than in reality.......

The T-shirt is great quality! The cotton is thick and does not lose its shape. I bought this as a gift last Christmas and since then it has been washed many times and I haven't seen any stretching or tears. The size fits perfectly. The printing is excellent. The colours and the design were exactly as shown in the picture. One year after, it hasn't faded due to washing.

I really like the design but I'm not sure the white base really took as you can see pink through her fur/bikini. So that was a little disappointing. That's more on the printing side though than the actual design, the design is really great, Cutey Bunny looks so beautiful! If you're thinking of getting this then I'd say just go for a white T-shirt and you should be fine.
