My friend is getting married and honestly, I’ve put on some weight lately. My mom keeps saying, ‘wear dark colors, so your belly doesn’t show,’ and my aunt is making subtle remarks like, ‘choose something a bit looser.’ But I still want to wear a colorful and bold dress. Do you think I should be brave and not pay attention to what they say? I’m a bit afraid of going overboard, but what if it actually looks good?
I think you shouldn’t go for such dark colors, my dear. Sure, they say darker shades look more elegant on someone with a bit more weight, but bright colors add energy to everyone. Especially at a place like a wedding! Why not try a light pink or red? 
If I had a daughter, I swear I would buy her plenty of things, plus a nice pair of heels. You can’t really be comfortable in things that make you look bulky, you end up regretting it all day long 
So now you’re saying you’ve gained weight, but you still want to wear something daring, alright great. But what if they aren’t just throwing shade and are actually giving decent advice? Sometimes a person can’t look at their own body objectively 
I think the main thing here is to feel comfortable. Be colorful, but choose a style that doesn’t cling too much to your body shape. The fabric should be stretchy so it doesn’t restrict you while moving. If you keep the chest area not too revealing, you’ll feel more at ease independent of your mother’s warnings, after all, it’s a wedding environment.
let me add this; I visited a few stores today. I tried on a dark blue dress, but it felt too heavy on me. It seemed like it made me look older. Honestly, I still have the urge to try something bold 
Don’t think too complicated, look, I’m suggesting directly: A midi-length dress with a cinched waist and a V-neck. It should be neither too tight nor too loose. You can look at shades of green for color; it’s both energetic and balanced
You know, the saying that your chest shouldn’t be too exposed is something I literally heard from my mom! They say it as if they’re trying to protect you, but it feels like extra pressure at the same time. I think you should find a style that makes you feel good, don’t conform to what your mom or anyone else wants.
It seems like Valla has spoken more sensibly than your aunt. She’s saying not to wear dark colors if you don’t want the belly to show; she’s not hinting, just saying it outright. If you say to wear loose clothes, it would be too exaggeratedly baggy. You can actually find a middle ground between the two of them 
What kind of logic is this? The girl isn’t going to her own wedding, she’s going to her friend’s wedding. You’re complaining that a dress might be too extravagant. Should her self-confidence take a vacation or something? Just be a bit brave and get it over with
