With a background in fine arts and a reverence for minimalist structure, Mona’s designs bring sculptural elegance to everyday wear. Each piece speaks of precision, from the crispness of the collar to the clean fall of the fabric.
Whether you gravitate toward her classic Button-Downs or the more fluid Asymmetric Cuts, these shirts are made for women who appreciate detail, tailoring, and timeless design.
