Short answer. Generally no. Article 1070 shields wedding gifts of jewelry, clothing, and outfit given by parents and ascendants from being reduced as inofficious donations, except for whatever portion of them exceeds one-tenth of the amount the giver could freely dispose of by will.
What the law says
Wedding gifts by parents and ascendants consisting of jewelry, clothing, and outfit, shall not be reduced as inofficious except insofar as they may exceed one-tenth of the sum which is disposable by will.

Why wedding gifts get special protection
When a person dies leaving less than the legitime reserved for compulsory heirs, donations made during his lifetime can be reduced as inofficious to restore what the heirs are owed. Article 1070 carves out a protected category for this situation: wedding gifts of jewelry, clothing, and outfit given by parents and ascendants to a child or descendant on the occasion of marriage. These gifts are treated differently from ordinary donations precisely because they mark this life event, and the law does not want every jewelry set or wedding outfit given by a parent exposed to reduction the way other donations are.
The protection has a ceiling: one-tenth of the disposable portion
The exemption is not unlimited. Article 1070 shields these wedding gifts except insofar as they may exceed one-tenth of the sum which is disposable by will. In other words, only the value of jewelry, clothing, and outfit that stays within ten percent of what the giver could have freely willed away is untouchable; any excess above that one-tenth is treated like an ordinary donation and can be reduced if needed to complete the legitime of compulsory heirs.
Applying it to your jewelry and clothing
If what your parents gave you for your wedding was jewelry, clothing, and outfit — the exact categories Article 1070 names — the gift is protected up to one-tenth of the portion of their estate that they could dispose of freely by will. Only the value exceeding that one-tenth would be exposed to reduction as inofficious, and only if reducing it is actually necessary to satisfy a compulsory heir's legitime that the estate would otherwise fall short of.
What falls outside this specific protection
The exemption is worded narrowly around three categories — jewelry, clothing, and outfit — given specifically as wedding gifts by a parent or ascendant. Other property given on the same occasion, or gifts from someone who is not a parent or ascendant, do not fall under this particular rule and would be evaluated under the ordinary rules on reducing donations that impair the legitime, without the one-tenth allowance Article 1070 provides.
