I would second the suggestion to try a bronzing spray. At this time of year... everyone is going to know it's fake if you take it too far and then you'll look potentially out of place in the wedding party.
If you are going for the super tan look, then tan away
just saying, bronzing spray add a natural tone to your skin without looking orange, going to a tanning salon may give too much of a tan and not look natural.
also... aside from this: tanning causes cancer. the most recent Miss. America has many scars from having skin cancer removed, she's young and only had been tanning for a little over a year... just goes to show how quickly skin cancer can take hold when exposed to harmful rays.
PSA:
Tanning salons are NOT any safer than sitting under the full sun.
good luck with being in the wedding.
