Hello Fabbers , it has been a while since I last posted. I’m looking for practical advice on what to wear to my daughter’s debutante ball in the second half of May. Special occasion dressing is very rare for me, and I don’t have anything appropriate for an event at this formality level, so I’m starting completely from scratch.

To give a sense of the dressiness and overall aesthetic, here are two photos of my daughter in the dresses she tried. She will also be wearing above‑the‑elbow white gloves and white shoes so the look is very classic and traditional.

I would really appreciate guidance on what styles, silhouettes, colours, and fabrics are suitable for a mother at this type of event.

What I know so far:

• A long gown is required
• It’s a very formal evening event at the Vienna Rathaus
• I’m open to both buying and renting

I would love advice on:

• Flattering silhouettes for formal gowns
• Appropriate colours that work well for me
• Fabrics or details that look elegant without being overly flashy
• Shoe styles that are comfortable enough for a long evening
• Simple, polished hair ideas (I prefer low‑maintenance styles)
• What level of accessories is typical for this kind of event
• Supportive underwear or any other details I am forgetting

Since I’m starting from zero, any guidance on what to look for, and what to avoid , would be very helpful.
Thank you in advance!
