The question is do I need that gorgeous heavy dinner gown during my vacation? The answer is NO, a big fat NO. Vacations are occasions where you need to unwind and unload. So do not carry heavy dresses unless you are attending a marriage and cannot do without the dress you purchased specifically for the occasion.
When you are traveling you will still need multiple outfits. For an average 4-5 day vacation you will need about 10-14 outfits. But that never means 10-14 dressers or pairs of clothing. You can mix and match 6 different garments to make 12-20 different types of outfits. So planning your outfits ahead of your travel is very important.
Learn about the activities you will be engaging in during the vacation. Since this is summer time most of us will be encountering a lot of water so plan what outfits can be teamed up for water activities. Seriously 3 swimsuits are not required. You can even do with NO swimsuit and combine a stole with innerwear to make a cute and fashionable swimwear.
Take along fewer bottoms in neutral colors that can be mixed with almost anything. Take more tops than bottoms, especially those that are versatile and can be worn in different situations. A floral print shirt over a striped t-shirt works like a vest and can also be worn single with sleeves rolled up. Don’t carry very light colors they get dirty fast.
One quick tip if you are having problems with limiting your outfits is sticking to one or two color theme. I used Blue and Yellow on my last trip and it was noticed better and appreciated by my friends and family more.
Plan your day wise look and the places you will visit, accordingly pack your clothes and look at repeating them by either adding scarf, jacket or wearing it differently. Always carry one pair extra so even it rains etc, you are sorted.
