Ladies evening dresses are gowns that they wear for formal functions or semi-formal events and parties. They are less over the top than ball gowns and are usually full length and have a flowing style. Short evening dresses are becoming more popular, unless your event is very formal, as they are fun and flirty, but staying with the classic look is a safer bet.
Don’t ask your significant other or she’ll know you’re up to something. Look in her wardrobe at something she’s worn recently and you know fits well. Unless you want to spend weeks on this little project you need a quick way to narrow down the vast range of styles available. stick with something longer than mid calf. spaghetti straps and halter necks are very popular, especially in the summer months. For a more dramatic look, go for a ladies evening dress with only one shoulder strap. For women that hate having their arms on show, find something with short or long sleeves or plan on buying a bolero jacket or shrug as well. if your wife is a bit more reserved, stick with dresses that offer moderate coverage of the back and cleavage. If your wife is a party girl, buy a bold dress with a plunging neckline, an open back and thigh high split. if your wife is comfortable with her bottom and thighs, go for a mermaid or sheath shape gown. If she prefers to cover up in these areas, an empire waist or A-line dress would be perfect.
Overall simple is your safest option. Avoid anything overly embellished or fancy.
