4 reviews for Official The Most Difficult Thing In Life Is To Know Yourself T-Shirt

  1. Maya David Sedaris –

    I have always hated shopping for shirts. Nothing ever fits right and all I want to do is cry. I always feel that people that are a 14 or smaller had it made and even though I’m not a big woman, like many, I have a few areas that some designers here in the U.S. forget about. I found Yours shirts about a month ago and was completely excited. I ordered a couple of shirts at first and loved the way they fit and my problem areas…..well lets just say your shirts made me feel sexy for once in my life. I have since placed more orders and AM THRILLED TO shirts SHOP for the first time in my life. FINALLY, my light at the end of the tunnel! Thank you so much for thinking of us big boned women and giving us what we finally want!

  2. Isaac James Herriot –

    Fast shipping and best of all, a great gift for photogeeks

  3. William Liam –

    Excellent service, speedy response ( needed to exchange) and great quality. Thank you

  4. Kami Garcia Irene –

    I loved the packing so much, it’s really beautiful and made me feel like I was opening the world’s most luxurious shirts! The t-shirt itself is lovely; heavy cotton, double stitching, looks fabulous but also durible which was what I wanted. The quality really reflects the price, which I an relived about because I’m a student and I’ve never spent more than £10 on a t-shirt. I’m looking forwards to buying a more loose fitting one for different outfits. Thanks so much for such a beautiful product!
