Wear a Brown Scapular. Have it imposed by a priest.
Although there is nothing objectively wrong with wearing a Rosary,,, Rosaries should be prayed, rather than worn; and like N said, you don't need beads to pray the Rosary.
A priest "invests" you (not imposes you) with a Brown Scapular. The word comes from the root word of "vestment," or garment, because the Scapular is Our Lady's garment.
Rosaries should be prayed rather than worn, yes. So if you find you pray it more regularly when you wear it, does that mean you shouldn't wear it and therefore pray it less, just to be scrupulous about not wearing it? What does that achieve?
As for "you don't need beads to pray the Rosary," that is a
half truth.
You can physically pray the Rosary without beads, but you won't get the indulgence!
The prayer of the Rosary receives the highest indulgences under the following conditions:A) You are in the state of sanctifying grace when you pray your Rosary
B) You hold a BLESSED Rosary in your hands if you are able (if you are not able to hold it, then having the intention of holding it may suffice), and the rosary should be your own, personal rosary if possible because habitually borrowing a rosary shows that you do not assent to the commitment of personal involvement of the practice; if you are driving a car, for example, someone else can hold the rosary so it isn't a distraction for you while operating the vehicle, and you both get the same indulgence you would get if you held the rosary yourself.
C) You move your lips to the words, at a minimum, but preferably you actually voice the prayers out loud, and you DON'T RUSH the words, but speak them thoughtfully and precisely, not mumbled and slurred
D) You kneel, preferably before the Blessed Sacrament
E)You make a conscious effort to consistently keep your mind on the meditations of the mysteries and deliberately will to avoid any distractions, whatever they may be
F) When with one or more others, you recite the prayers antiphonally, that is, the person leading the Rosary only says the first half of each prayer (Our Father, Hail Mary, Glory Be -- but the rest can be prayed in unison) and the other person(s) says the second half, or response, of each prayer
G) You pray the entire introductory prayers, the 5 decades and the concluding prayers in one continuous session without interruption, if possible -- if you are interrupted beyond your control, then you attend to your duty as required, and return to the prayer of your Rosary at the first opportunity, so as to finish it within one day, if at all possible.
H) You have received from your priest permission to pray the Rosary daily as a condition of your Brown Scapular enrollment, in lieu of having to pray the Divine Office or the Little Office of the Blessed Virgin Mary every day.
I) You pray the Rosary with another person, or some number of others, in which case, each one of you receives the indulgence of the entire group; such that the number of people squared (times itself) is the number of Rosary indulgences of the whole group. One person alone receives one Rosary indulgence, but 2 people receive 2 indulgences each; 3 receive a total of 9 indulgences as a group, and 10 receive a grand total of 100 indulgences, and 100 people receive 10,000 Rosary indulgences as a group!
After all of that, the Rosary is the most highly indulgenced prayer in the Catholic Church, outside of Holy Mass, even if prayed alone. But without the beads in hand, or not kneeling, or not before the Blessed Sacrament, or not moving the lips, etc., you give up a lot of graces.
There is no indulgence for wearing a rosary. But if wearing it makes you more likely to pray it, or gives you the reminder you need to pray it, or keeps it at hand more readily so you can easily pray it, then wearing your rosary is
better than not wearing it. But if you have been ordered under obedience to not wear your rosary, you gain virtue by being obedient to your legitimate superior.
