there is nothing wrong with getting a sensible tatto if you really want one. There is also nothing wrong with mark-up or jewellery.
"I rise early, O my Husband Lord, to behold Your Vision. Eye make-up, garlands of flowers, and the flavor of betel leaf, are all nothing but dust, without seeing You. ||3||" p.1094
"O my companion, I have prepared everything: make-up, garlands and betel-leaves. I have embellished myself with the sixteen decorations, and applied the mascara to my eyes. If my Husband Lord comes to my home, then I obtain everything. O Lord! Without my Husband, all these adornments are useless. ||3|| Very fortunate is she, within whose home the Husband Lord abides. She is totally adorned and decorated; she is a happy soul-bride. I sleep in peace, without anxiety; the hopes of my mind have been fulfilled." p. 1361
"O Enticing Lord, I cannot sleep; I sigh. I am adorned with necklaces, gowns, ornaments and make-up. I am sad, sad and depressed. When will You come home? ||1||Pause|| I seek the Sanctuary of the happy soul-brides; I place my head upon their feet. Unite me with my Beloved. When will He come to my home? ||1||" Sri Guru Granth Sahib JiJ p. 830
"All my desires have been fulfilled, meeting the Lord face-to-face; I am His servant, I serve at His feet. My necklaces, hair-ties, all decorations and adornments, are in singing the Glorious Praises of the unseen, mysterious Lord. I long for loving devotion to the Lord of the Universe, and so the Messenger of Death cannot even see me." Sri Guru Granth Sahib JiJ p929Reference:: Sikh Philosophy Network http://www.sikhphilosophy.net/sikh-youth/8832-tattoos.html
